What Is Feature Detection?

Feature detection is a concept in computer vision and image processing. It refers to the use of computer to extract image information to determine whether the points of each image belong to an image feature. The result of feature detection is to divide the points on the image into different subsets. These subsets often belong to isolated points, continuous curves, or continuous regions.

So far, characteristics are not universal and precise. The precise definition of a feature is often determined by the problem or application type. Feature is a

After a feature is detected, it can be extracted from the image. This process may require many image processing computers. The result is called feature description or feature vector. ^[2]
