Technologies are not only born to provide the goodness to humans, as few people make misuse of it and try to create illegal things that can embarrass them or hurt their sentiments deeply. Deepfakes, an AI-backed technology, is one that comes into the limelight due to wrong reasons defamed many people in the last few years.
What is Deepfake Technology?
Deepfake is an AI-supported technique to create ultra-realistic fake videos of people by swapping their faces other person saying and doing things that they haven’t actually done. It includes images, videos and audios to combine with images and videos onto source images or videos. Porn videos having the mocked face of popular celebrities on the adult star are one of the well-known examples of deepfakes.
What Does Deepfake Mean?
Using the AI with high-powered computer a graphics processing unit (GPU) and time on their hands can create realistic fake videos is known as “Deepfakes”.
Deepfakes are not only limited to videos but the audio is also targeted to create such fake voice-based contents. Though, it is much more difficult to compare the face swapping but the voice of another person can be manipulated with any other person speaking something that is not originally said by him seems very original.
How Does Deepfake Technology Work?
Neural network based technology is used to make Deepfake videos. The deep learning process is used into deepfake creation that is kind of ultramodern application of neural net simulation to massive data sets. Primarily neural networks are capable to “learn” to perform tasks by considering, generally without being programmed with any task-specific rule.
Deepfakes use the human tendency through generative adversarial networks (GANs) in which two machine learning models are trained with the data sets to create fake videos at the same time also detect fake videos. The forger ML model keeps continuing creating fake videos until the second model fails to detect the forgery.
How Deepfake Videos are Created
The larger the quantity of training data sets it would be easier for a forger to create deepfakes that can be believed easily. Political celebrities and Hollywood’s popular actresses became the victims of Deepfake technology misrepresenting their personalities and pose a grave threat to women not prominent could have their reputations damaged by the depiction in involuntary deepfake pornography or revenge pornography.
What Software is Used to Make Deepfakes?
There are many software available in the market to create deepfakes. One of them is FakeApp that allows the normal person to make the deepfake content, though this website has been banned but still many apps are active in the market.
Samsung AI has recently developed a new artificial intelligence system that can generate a fake clip by feeding it as little as one photo. Usually requires big data sets of images in order to create a realistic forgery but here you don’t need a huge amount of images or videos to create deepfakes misusing the AI for humans.
Samsung has used this technology into famous Leonardo Da Vinci painting of Mona Lisa in which it has assigned a series of ‘facial landmarks’ to the portrait and then applied an algorithm that has access to metadata from a vast amount of image banks to form a different ‘movements’ of the Mona Lisa’s head that you can spot below.
Popular Deep Fake News
The most popular Deepfake news was a fake video of the former US president Barack Obama in which he was expressing a profanity-laced opinion on US president Donald Trump.
Similarly, a fake video of Steve Buscemi came into the market in which her face was superimposed onto Jennifer Lawrence while speaking at the Golden Globes award show.
Apart from this, many other celebrities also became the news headlines due to deepfakes porn videos of popular actresses gone viral making millions of people excited to watch such contents. However, knowing the truth all the leading porn sites have removed such fake videos from their websites that were embarrassing such celebrities.
Deepfake in Pornography
Actually, Deepfake is a major threat to popular celebrities by creating their deep fake porn videos. The images of such celebrities or popular actresses are freely available on the Internet at their social media pages or other entertainment sites.
Many times such videos are created as revenge porn, in which deepfake creator needs a bunch of photos of the victim from various sources to superimposed the same on the body of a porn star and raunchy videos posted on adults websites.
Female celebrities including Taylor Swift, Natalie Portman, Emma Watson, Gal Gadot, Michelle Obama, Daisy Ridley, Meghan Markle, Sophie Turner and Kate Middleton had become the victims of deepfake pornography.
How to Detect Deepfake Video?
Detecting deepfakes is not possible with the normal human eye but there are few activities and signs that you can spot deepfake videos. Quality of video, irregular blinking of eyes, inconsistent skin tone, unnatural movement of the body or facial expressions and unusual changes in the background suchlike lighting conditions or color etc. are the major clues you can detect the deepfakes.
Video: Why Detecting Deep Fake is Difficult?
However, AI-enabled applications can detect such loopholes or fake videos using the same level of technology that has been used to create such contents. While on the other hand, human-powered deepfake detection services are also offered by companies to check and find out the fake videos, audio and texts with better accuracy.

These robots are well-trained to assist for checking the quality of crop and detect unwanted plants or weeds with picking and packing of crops at the same time capable to fight with other challenges faced by the agricultural labour force.
Companies like Blue River Technology and Harvest CROO Robotics are making such robotics machines that can control unwanted crops or weeds and help farmers in picking or packing of crops with higher volumes.
Controlling Pest Infestations
Pests are one of the worst enemies of the farmers damaging the crops globally before it is harvested and stored for human consumption. Popular insects like locusts, grasshoppers, and other insects are eating the profits of farmers and gobbling the grains meant for humans. But now AI in farming gives growers a weapon against such bugs.
AI and data companies are helping farmers to get alert on his Smartphones about the grasshoppers likely to descend towards a particular farm. AI companies using the new satellite images against pictures of the same using historical data and AI algorithm detects that the insects had landed at another location and farmers use such information after confirmation and timely remove the costly pests from their fields.
Soil and Crops Health Monitoring
Continues deforestation and degradation of soil quality are becoming a big challenge for food producing countries. But now a German-based tech startup PEAT has developed a deep learning based application called Plantix that can identify the potential defects and nutrient deficiencies in the soil including plant pests and diseases.
This app is working on image recognition based technology and you can use you your smartphone to capture the plant’s image and detect the defects into the plants. You will also get soil restoration techniques with tips and other solutions on short videos on this app.
Similarly, Trace Genomics is another machine learning based company provides soil analysis services to farmers. Such apps help farmers to monitor the soil and crop’s health conditions and produce a healthy crop with a higher level of productivity.
SkySquirrel Technologies acquired by another similar company VineView brought drone-based aerial imaging solutions for monitoring crops health. A drone is used to make a round of capturing the data from the vineyards field and then all the data is transferred via a USB drive from the drone to a computer and analyzed by the experts.
The company uses the algorithms to analyze the captured images and provides a detailed report containing the current health of the vineyard, generally the condition of grapevine leaves as these plants are highly prone to grapevine diseases like molds and bacteria helping farmers to timely control using the pest control and other methods.
Precision Farming with Predictive Analytics
AI applications in agriculture expanded into doing the accurate and controlled farming through providing proper guidance to farmers about optimum planting, water management, crop rotation, timely harvesting, nutrient management and pest attacks.
Video: What is Precision Farming?
While using the machine learning algorithms in connection with images captured by satellites and drones, AI-enabled technologies predict weather conditions, analyze crop sustainability and evaluate farms for the presence of diseases or pests and poor plant nutrition on farms with data like temperature, precipitation, wind speed, and solar radiation.
AI in agriculture not only helping farmers to automate their farming but also shifting to precise cultivation for higher crop yield and better quality while using less resources. Companies involved in improving the machine learning or AI-based products or services like training data for agriculture, drone and automated machine making will get technological advancement in future will provide the more useful applications to this sector helping the world deal with food production issues for the growing population.
The Main Purpose Of Image Annotations Is To Develop AI Model
The main purpose of image annotations is to highlight or capture the targeted object in a picture to make it recognizable for machines. Actually, image annotation is done for machine learning and AI to use the annotated images as a training data set while feeding with a deep learning algorithm and develop a fully functional AI model.
Objective Of Image Annotation
The machine learning is the processes to develop the AI-based models that can work itself without human intervention. And to train such machines a huge amount of training data is required for computer vision to identify the objects in images from the particular industry helping machines to recognize the similar images when used in real-life.
Types of Image Annotations
There are different types of image annotation techniques used to annotate such picture. And there are different types of free tools and software are available in the market to annotate the images as per the object dimension and requirement of the project. Actually, image annotation is important for machine learning and manual image annotation service is also available in the market you can choose as per your needs.
Bounding boxes, Semantic Segmentation, 2D or 3D Cuboid, Polygons, Polylines or Splines, Point and Landmark annotations are popular types of image annotation techniques used in this field to make the machine learning and AI model development possible. Anolytics.ai is one of the companies, providing the best quality image annotation service with human-powered data labeling and image recognition service at best quality.
Applications of Image Annotation
The main purpose of image annotations is to make the object recognizable for machines or computer vision. And there are many industries adopting AI and integrating the related technology into their sub-fields for automation to work faster with more efficiency.
A self-driving car is one of the best examples where annotated images have been used to train the model working into the auto functioning of such vehicles. The autonomous vehicles recognize the object on the street and move accordingly to avoid any crash. It is like making a child learn about new things with varied data sets so that it can be recognized easily when used in autonomous vehicles to drive on the road into real-world.
Healthcare is another important filed where annotated medical imaging used to develop such machines that can detect various types of maladies including life-threatening diseases like cancer at the initial stage of developments with better accuracy. Medical images like X-ray, MRI and CT Scan reports are annotated manually by humans that are used to train the machine learning to detect such diseases without the help of humans.
Apart from autonomous vehicle driving, there are many other fields, like healthcare, retail, agriculture, security surveillance and sports analytics are other areas image annotation is playing an important role to make the images easily recognizable for machines allowing machine learning developers to build a right model at affordable pricing.
The main purpose and objective of image annotation are well-described here with a various set of examples showing the use and purpose of image annotation in machine learning and AI. The right applications of image annotation are only possible when annotations are accurate so that models can get accurate data sets to learn and give the right predictions.
How Does AI Detect Cancer in Lung Skin Prostate Breast and Ovary?
Artificial Intelligence (AI) is really changing the world, especially in the field of healthcare and medical treatments where it can easily detect several deadly diseases like cancer and tumors at the initial stage of development with more accuracy compare to doctors.
Recently, Google has developed an AI model that can predict lung cancer from screening tests even better than human radiologists having an average of eight years of experience. AI-enabled such screening machines are now used at hospitals to diagnosis the different types of cancers and do you want to know how does AI detect cancer of different types.
How Does AI Detect Cancer?
Actually, AI-enabled models are developed with the help of a huge amount of healthcare training data in the form of medical imaging like X-Rays, CT Scan, MRI or other kinds of annotated reports. All these images showing the symptoms of cancer are feed into a machine learning algorithm to learn the patterns showing the early sign of cancer development and predict the chances of having this deadly disease in the future.
AI in Lung Cancer Screening
As per the WHO, lung cancer is the most common form of cancer across the world with 1.76 million deaths every year. An AI-oriented deep-learning system uses an algorithm and three-dimensional or 3D technology to examine the CT scans and generate the overall lung cancer malignancy prediction and identify subtle malignant tissue in the lungs.
While on the other hand, radiologists typically look through hundreds of 2D images within a single CT scan and cancer can be miniscule and hard to spot. But as per Google’s lung cancer detection model can factor information from previous scans, that can predict lung cancer risk because the growth rate of suspicious lung nodules can be indicative of malignancy. The more data is used in AI model training the accuracy would be higher.
How AI Detecting Skin Cancer?
Just like other cancers, AI can detect skin cancer accurately with day-by-day better deep learning model development improvements. Deep learning AI uses the pre-existing codified datasets in the form of images of malignant melanomas to detect skin cancers and moles and indicated the diagnosis for each image just like a dermatologist.
In most of the cases now the dermatologists were only 86.6% accurate at diagnosing skin cancer, while the AI-enabled computer can diagnose issues with a 95% accuracy. And the accuracy of prediction will improve if machine learning algorithms get precisely marked images through professional data annotation service providers.
AI in Breast Cancer Diagnosis
Breast cancer, one of the most common cancers among women is also getting amazing results from AI-enabled technologies. As per the team of researchers at the Massachusetts Institute of Technology developed an AI-based deep-learning model can predict a woman’s breast-cancer risk up to five years in advance.
In AI breast cancer detection, deep learning model can identify patterns in mammograms from thousands of annotated images driving the future cancer growth. AI Models detect patterns that represent the influence of genetics, hormones, pregnancy, lactation, diet, weight loss, and weight gain which too subtle for the human eye to detect. AI in breast cancer treatment is becoming successful with more accurate data sets and algorithm learned the subtle patterns in breast tissue that are precursors to malignant tumors.
AI in Prostate Cancer Diagnosis
Affects 1 in 9, Prostate Cancer is one of the most common cancers among the men can be also now detected with the help of AI-enabled machines. AI can detect prostate cancer by analyzing the MRI scans of men having prostate cancer that are fed into the system with deep learning or machine learning algorithms learning to assess and classify tumors.
AI stops prostate cancer by diagnosing the causes and helps doctors to take preventive measures and provide timely treatments. Radiologists using the medical images can detect such disease but the use of AI in radiology is giving the healthcare sector a new dimension by comparing and analyzing the millions of similar images before predicting the prostate cancer to make sure the accuracy level should be acceptable.
AI in Ovarian Cancer Diagnosis
Ovarian cancer is one the sixth most common cancer among the women worldwide which usually affects women after the menopause or those with a family history of the disease. During research in the UK, AI technology used to carefully identify and track the shape of about 150 million different cells in total found within the patients.
The AI-enabled system can scan the shape and content of the cells within the tumor or primarily focused on the nuclei and discovered some anomalies found the nuclei of cells are round, or a bit oblong revealing there were “small patches with misshapen nuclei” in some of the ovarian tumor samples facilitating doctors provide timely treatments.
AI in healthcare is playing a decisive role, especially in detecting such life-threatening diseases at the early stage of development allowing patients to get the timely treatments and recover without any risk. Further, with the more improvement in AI-enabled machine learning model development process and availability of quality training data will also help machines detect such diseases with more accuracy and at more earlier times.
