How Computer Vision Used

The most used computer vision models is facial recognition. It is a way to identify or confirm an individual’s identity using their face. Facial recognition is a category of biometric security, and other forms of biometric software include voice recognition, fingerprint recognition, and eye retina or iris recognition. You can find it almost everywhere nowadays. Next is edge detection or edge detection.

It is one of the types and varieties of computer vision which is an image processing technique used to identify points in a digital image with discontinuities. As for the points where the brightness of the image varies greatly these are called the edges (or boundaries) of the image. In addition, there are several methods used in edge detection, such as:

Prewitt edge detection
Sobel edge detection
Laplacian edge detection
Canny edge detection

Then, there is also pattern recognition or pattern detection. It is the process of recognizing patterns using machine learning algorithms. Pattern recognition can be defined as data classification based on the knowledge that has been obtained or statistical information taken from the pattern or its representation. One of the important aspects of pattern recognition is its potential application.

Examples include speech recognition, speaker identification, multimedia document recognition or Multimedia Document Recognition (MDR), and automated medical diagnosis. Image classification in computer vision is the process of predicting a particular class, or label, for something defined by a set of data points. Image classification is part of the classification problem, where all images are labeled. For example, an image might be classified as a day or night shot. In the same way, images of cars and motorcycles will also be automatically placed into their groups.

The last type of computer vision that we will explain here is feature matching. This is a general image matching, part of many computer vision applications such as image registration, camera calibration, and object recognition is the task of establishing a correspondence between two images of the same scene or object. This general approach to feature matching consists of detecting a set of points of interest each associated with an image descriptor from the image data. After the features and their descriptors have been extracted from two or more images, the next step is to create some initial feature matches between these images.
