Abstract:

Pseudo-coloring, a common task in image processing is used to color a grayscale image or to modify an existing color image with an intention of enhancing visual quality, imparting a visual appeal and highlighting specific features in the image. This paper presents a review of recent pseudo-coloring techniques in which the color is transferred from a source color image to a grayscale one. The techniques that we discuss here include the user interactive, semi-automated and automated pseudo-coloring approaches. The user interactive pseudo-coloring methods demand a complete user effort in selecting the source image as well as in color transfer process, whereas the task of user in semi-automated pseudo-coloring approaches is confined only to the selection of source image. In automated pseudo-coloring approaches, the user does not take any effort since the whole process is automatic. The performance of various pseudo-coloring techniques has been compared qualitatively based on the corresponding colored results and MOS values, and thereby identify the appropriate methods in each category.
