techniques and its application in medical image enhancement. In this paper, conventional …

Real-world optimization problems demand an efficient meta-heuristic algorithm which
maintains the diversity of solutions and properly exploits the search space of the problem to …

In the field of image processing, there are several problems where the efficient search has to
be performed in complex search domain to find an optimal solution. Image enhancement …

Contrast enhancement techniques that are proposed in the literature are devised to
enhance image quality so as to provide better details for different image processing tasks …

In this paper, a novel image sub-division and quadruple clipped adaptive histogram
equalization (ISQCAHE) technique is proposed for the enhancement of low exposure …

This article introduces a novel optimally selected plateau limit (PL)-based histogram
modification framework. This approach preserves the brightness and improves the contrast …

Background In this paper, a new method for optimal enhancement of the contrast of a
medical image is proposed. The main idea is to improve the Gamma correction method to …

Glaciers in the northwestern Himalayan region of Jammu and Kashmir have been reported
to be retreating at higher rates as compared to other parts of the Himalayan arc. This study …

A satellite image transmitted from satellite to the ground station is corrupted by different
kinds of noises such as impulse noise, speckle noise and Gaussian noise. The traditional …
