Abstract

In this paper, hybrid approaches for quality enhancement of images
compiled from Contrast Limited Adaptive Histogram Equalization
(CLAHE) and image interpolation are presented. Adaptive histogram
equalization is employed for contrast enhancement, while image
interpolation is used for resolution enhancement. Both the CLAHE and
image interpolation are used interchangeably to check the most
suitable scheme for quality enhancement of images. The utilized
interpolation techniques during paper are polynomial-based
techniques. Simulation results have proved that the application of
CLAHE firstly enhances the image quality in a better way.
