Image recognition AI: from the early days of the technology to endless business applications today

This is why many e-commerce sites and applications are offering customers the ability to search using images. Annotations for segmentation tasks can be performed easily and precisely by making use of V7 annotation tools, specifically the polygon annotation tool and the auto-annotate tool. A label once assigned is remembered by the software in the subsequent frames. Lawrence Roberts has been the real founder of image recognition or computer vision applications since his 1963 doctoral thesis entitled “Machine perception of three-dimensional solids.” It took almost 500 million years of human evolution to reach this level of perfection. In recent years, we have made vast advancements to extend the visual ability to computers or machines.

As we’ve mentioned earlier, to make image recognition work seamlessly it is crucial to train it well and use proper learning algorithms and models. As of now there are three most popular machine learning models – support vector machines, bag of features and viola-jones algorithm. Speaking about AI powered algorithms, there are also three most popular ones. So let’s take a closer look at all of them right away and see what makes them really useful. The first steps towards what would later become image recognition technology were taken in the late 1950s.

And while several years ago the possibilities of image recognition were quite limited, the introduction of artificial intelligence and deep learning helped to expand the horizons of what this mechanism can do. Image recognition is ideal for applications requiring the identification and localization of objects, such as autonomous vehicles, security systems, and facial recognition. Image classification, however, is more suitable for tasks that involve sorting images into categories, like organizing photos, diagnosing medical conditions from images, or analyzing satellite images.

Even then, we’re talking about highly specialized computer vision systems. The universality of human vision is still a dream for computer vision enthusiasts, one that may never be achieved. It requires significant processing power and can be slow, especially when classifying large numbers of images. Many people have hundreds if not thousands of photo’s on their devices, and finding a specific image is like looking for a needle in a haystack. Image recognition can help you find that needle by identifying objects, people, or landmarks in the image.

How is AI Trained to Recognize the Image?

TensorFlow is an open-source platform for machine learning developed by Google for its internal use. TensorFlow is a rich system for managing all aspects of a machine learning system. The system trains itself using neural networks, which are the key to deep learning and, in a simplified form, mimic the structure of our brain. This artificial brain tries to recognize patterns in the data to decipher what is seen in the images.

Image recognition technology has found widespread application across many industries. In the healthcare sector, it is used for medical imaging analysis, assisting doctors in diagnosing diseases, detecting abnormalities, and monitoring patients’ progress. Image recognition algorithms can identify patterns in medical images, helping healthcare professionals make more accurate and timely diagnoses. These algorithms process the image and extract features, such as edges, textures, and shapes, which are then used to identify the object or feature. Image recognition technology is used in a variety of applications, such as self-driving cars, security systems, search engines.

Although the benefits are just making their way into new industry sectors, they are heading with a great pace and depth. With the application of Artificial Intelligence across numerous industry sectors, such as gaming, natural language procession, or bioinformatics, image recognition is also taken to an all new level by AI. Convolutional Neural Networks (CNNs) have proven to be highly effective in improving the accuracy of image recognition systems. These models have numerous layers of interconnected neurons that are specifically designed to extract relevant features from images.

In computer vision, feature extraction is a crucial step in most image recognition tasks. Deep learning is a subset of machine learning that consists of neural networks that mimic the behavior of neurons in the human brain. Deep learning uses artificial neural networks (ANNs), which provide ease to programmers because we don’t need to program everything by ourselves. When supplied with input data, the different layers of a neural network receive the data, and this data is passed to the interconnected structures called neurons to generate output. Image recognition technology has become an integral part of various industries, ranging from healthcare to retail and automotive. This powerful tool leverages artificial intelligence (AI) algorithms to analyze and interpret visual data, enabling machines to understand and interpret images just like humans do.

This defines the input—where new data comes from, and output—what happens once the data has been classified. For example, data could come from new stock intake and output could be to add the data to a Google sheet. Images—including pictures and videos—account for a major portion of worldwide data generation. To interpret and organize this data, we turn to AI-powered image classification.

Several deep learning frameworks and libraries, such as TensorFlow, PyTorch, and Keras, provide developers with the tools and resources needed to build and deploy image recognition models. These frameworks offer pre-trained models that can be fine-tuned for specific applications, reducing the time and effort required for training from scratch. An example of the implementation of deep learning algorithms, identifying a person by picture, is FaceMe, an AI web platform, also developed by NIX engineers. It helps photographers to sort photos, search images with specific people, and filter images by emotions. Image recognition in the area of computer vision (CV) and machine learning (ML) is the ability of the computer to understand what is depicted on an image or video frame and identify its class.

Bag of Features Models

In reality, only a small fraction of visual tasks require the full gamut of our brains’ abilities. More often, it’s a question of whether an object is present or absent, what class of objects it belongs to, what color it is, is the object still or on the move, etc. Each of these operations can be converted into a series of basic actions, and basic actions is something computers do much faster than humans. Open-source frameworks, such as TensorFlow and PyTorch, also offer extensive image recognition functionality.

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().
