| 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. | ||||
