A Review on 2D Image Representation Methods

Abstract

Image Representation is the process of generating descriptions from the visual contents of an image. There is a wide range of image representation methods which have been proposed in the past few decades. Some of these methods are designed for specific application areas while others are more generalized and can be applied in various fields. Each of the image representation methods is unique in its own way and has its advantages and drawbacks. This paper does a brief review on different existing two dimensional image representation methods by focusing its approach, advantages, limitations and applications. The analysis shows that most of the representations is based on machine perception model which cannot be understandable by a human being just by looking through his eyes. The paper ends with the suggestion of introducing a representation which can understandable by both a human and machine.
