AI-based OCR algorithms use machine learning to enable the recognition of characters and words in images. The key idea behind convolution is that the network can learn to identify a specific feature, such as an edge or texture, in an image by repeatedly applying a set of filters to the image. These filters are small matrices that are designed to detect specific patterns in the image, such as horizontal or vertical edges. The feature map is then passed to “pooling layers”, which summarize the presence of features in the feature map.
Automated adult image content moderation trained on state of the art image recognition technology. For instance, Google Lens allows users to conduct image-based searches in real-time. So if someone finds an unfamiliar flower in their garden, they can simply take a photo of it and use the app to not only identify it, but get more information about it. Google also uses optical character recognition to “read” text in images and translate it into different languages. Its algorithms are designed to analyze the content of an image and classify it into specific categories or labels, which can then be put to use.
Two years after AlexNet, researchers from the Visual Geometry Group (VGG) at Oxford University developed a new neural network architecture dubbed VGGNet. VGGNet has more convolution blocks than AlexNet, making it “deeper”, and it comes in 16 and 19 layer varieties, referred to as VGG16 and VGG19, respectively. Then, we create an object of the respective feature extraction technique using cv2.xfeatures2d.SIFT_create(), cv2.xfeatures2d.SURF_create(), and cv2.ORB_create(). We then use the detectAndCompute() function to detect keypoints and compute descriptors for the image. Finally, we draw the detected keypoints on the image using cv2.drawKeypoints() and display the image using cv2.imshow().
A must-have for training a DL model is a very large training dataset (from 1000 examples and more) so that machines have enough data to learn on. There’s also the app, for example, that uses your smartphone camera to determine whether an object is a hotdog or not – it’s called Not Hotdog. It may not seem impressive, after all a small child can tell you whether something is a hotdog or not. But the process of training a neural network to perform image recognition is quite complex, both in the human brain and in computers.
Today, we are going to build a simple image recognition system using the Python programming language. You may be wondering why Python when there are many languages that can be used to create AI systems. Python has a number of versatile and useful libraries that developers can use to achieve that goal and make the process easier than some of its competitors. So today, we are going to go through the creation of a simple image recognition system so that you can get familiar with the various AI libraries and tools Python has to offer. Image recognition is one of the quintessential tasks of artificial intelligence.
AI algorithms enable machines to analyze and interpret visual data, mimicking human cognitive processes. By leveraging AI, image recognition systems can recognize objects, understand scenes, and even distinguish between different individuals or entities. Image recognition technology has become an integral part of various industries, ranging from healthcare to retail and automotive.
Anonymizing and encrypting personal information, obtaining informed consent, and adhering to data protection regulations are crucial steps in building responsible and ethical image recognition systems. Computer vision is what powers a bar code scanner’s ability to “see” a bunch of stripes in a UPC. It’s also how Apple’s Face ID can tell whether a face its camera is looking at is yours. Basically, whenever a machine processes raw visual input – such as a JPEG file or a camera feed – it’s using computer vision to understand what it’s seeing. It’s easiest to think of computer vision as the part of the human brain that processes the information received by the eyes – not the eyes themselves.
Solutions of this kind are optimized to handle shaky, blurry, or otherwise problematic images without compromising recognition accuracy. Face and object recognition solutions help media and entertainment companies manage their content libraries more efficiently by automating entire workflows around content acquisition and organization. A deep learning model specifically trained on datasets of people’s faces is able to extract significant facial features and build facial maps at lightning speed. By matching these maps to the approved database, the solution is able to tell whether a person is a stranger or familiar to the system. Our mission is to help businesses find and implement optimal technical solutions to their visual content challenges using the best deep learning and image recognition tools. We have dozens of computer vision projects under our belt and man-centuries of experience in a range of domains.
