Comprehensive Study on Shape Based Feature Extraction

Abstract

Worldwide, digital image processing has produced a large number of images. Shape is a key visual property of an object that must be recognized in a digital image before it can be identified. Employing a shape feature, find an object in an image. Object recognition and computer visualization both heavily rely on feature extraction. To the knowledge of researchers, there have been several periods of research, but there isn't a strategy for feature extraction that is widely accepted. The form aspects of feature extraction approaches are used in this research to categorize them. There are several methods for extracting features, including form descriptors, global features, structural features, etc.
