Computer Vision is the study of how computers can replicate the human visual system in various ways. It is the most well-known and major subset of Artificial Intelligence (AI) that collects and evaluates data from pictures or videos. Obtaining pictures, screening them, analyzing them, recognizing them, and eventually extracting meaningful information are all phases in this process.
This approach enables computers to perceive, analyze, and recognize any sort of visual input and respond accordingly. In this technique, all visual inputs are translated into clear descriptions, which are subsequently transformed into language that computers can understand and use to feed the machine’s decision-making process. The ultimate goal of computer vision technique is to teach and empower robots to extract information from mere pixels.
Current developments in neural networks and deep learning techniques have largely scaled the performance and capabilities of visual recognition systems.
We’ve listed the 5 most prevalent computer vision applications:
1- Image Classification
Image classification is a subset of Computer Vision and Artificial Intelligence, a collection of technologies that machines use to recognize and analyze pictures in order to automate desired activities. This technique is capable of recognizing places, people, objects, and a variety of other elements in a picture and drawing inferences from them by analyzing them.Image classification is perhaps one of the most well-known applications in computer vision. It allows a given image to be classified as belonging to one of a set of predetermined categories. Let’s consider the following example: we want to categorize photographs depending on whether or not they belong to a tourist destination. Assume a classifier is built for this purpose and a photograph of the Dubai Fountains is provided. The classifier will respond that the image is part of a collection of photographs of tourist destinations. This does not necessarily indicate that it has recognized the dancing fountains, but rather that it has seen photos of Dubai fountains and has been told that those photographs are a tourist attraction.
2- Object Detection
Object detection is a related task of computer vision and AI which involves recognizing objects in images. It primarily is a combination of 2 tasks: image classification and object localization. Image classification includes the identification of the class of a specific object in an image whereas object localization refers to identifying the location of one more object in an image by drawing bounding boxes around this extent.
3- Object Tracking
Object Tracking signifies the method of pursuing/following a specific object of interest or multiple items. Its goal is to follow an object in motion over time by using successive video frames as input. Computer vision in object tracking is helpful in a variety of human monitoring systems, from those that attempt to analyze consumer behavior to those that continually watch football or basketball players throughout a game.
4- Semantic Segmentation
Computer vision itself is a method of segmentation that breaks down images into pixel grouping, then labels and classifies them. It understands the character of every pixel in an image. For example, if we choose a natural landscape with people, roads, and cars, Semantic Segmentation attempts to semantically understand the role of each pixel in the image while also recognizing people, roads, cars, trees, and so on by delineating the boundaries of each object using dense pixel-wise predictions from our models.
5- Instance Segmentation
Following object detection, instance segmentation may be viewed as the following stage. In this situation, it is not just about identifying items in a picture, but also about producing an accurate mask for each identified object. Using an image of a real environment as an example, you can see how the instance segmentation algorithm finds masks for certain automobiles, people, trees, and so on. In France, for example, it is illegal to expose children in the media without their parents’ explicit agreement. When small children are seen in interviews or photographs made outside, it is easy to blur away their faces on television or video using instance segmentation techniques.
The reason why computer vision is challenging in several aspects
With the aid of deep learning, computer vision has advanced quickly in recent years, qualifying its capacity to recognize objects, segment pictures, and extract important context from a given scene. If we look at it from a biological standpoint, computer vision technology attempts to develop computational representations of the human intrinsic visual system. From an engineering standpoint, the goal of computer vision is to create autonomous applications that can perform some of the tasks that the human visual system can perform, and even outperform it in some cases. However, given the current state of affairs, getting computer vision to its final maturity is very challenging.
Computer vision is already altering and reshaping numerous sectors. Some things to look forward to in computer vision technology in the future:
Computer vision research is advancing toward the development of improved algorithms capable of automating activities involving visual cognition. Computer Vision algorithms are increasingly gaining the ability to handle a wide range of tasks, and they are achieving and enhancing the generalization of visual representations.
Acquiring human capabilities
Because of advances in deep learning and artificial neural networks, computer vision will soon be capable of mimicking, if not outperforming, human eyesight in some tasks. It is expected to expand fast and become stunning as it begins to produce astonishing results in a variety of sectors and application settings.
