is a subset of Digital Image Processing or Image Processing in short. It deals with using various algorithms to improve and interpret pictures.
Image Processing is more than a subset; it is the forerunner of modern-day machine vision, supervising the creation of various rule-based and optimization-based algorithms that have led to the current state of machine vision.
The task of executing a series of operations on an image based on data gathered by algorithms to evaluate and alter the contents of a picture or the image data is known as image processing.

<h2>How does computer visionwork?</h2>
Here’s a quick graphic depiction that addresses the topic at its most fundamental level.
However—
While the three stages describing the fundamentals of appear simple, processing and interpreting a picture using machine vision is challenging. This is why:
A pixel is the smallest quanta in which an image may be split, and a picture is made up of many pixels.
Computers use an array of pixels to analyze pictures, with each pixel having a set of values that reflect the presence and intensity of the three basic colors: red, green, and blue.
A digital image is formed when all pixels are combined. As a result, the digital picture is transformed into a matrix, and is transformed into a study of matrices.
While the most basic algorithms handle these matrices using linear algebra, more complicated applications employ operations such as convolutions with learnable kernels and downsampling through pooling.
The numbers indicate the pixel values at the image’s specific coordinates, with 255 being a completely white point and 0 denoting a complete black point.
Matrix sizes are significantly greater for larger pictures.
While glancing at the image gives us a good sense of what it’s like, a glance at the pixel values reveals that the pixel matrix provides no information about the image!
To declare that this image depicts a person’s face, the computer must conduct complicated computations on these matrices and create connections with surrounding pixel components.
