In hazy weather, images and videos captured outdoor scenes often suffer from inadequate
visibility, low contrast, and color shift due to the atmospheric light scattering from the …

This paper proposes a novel variant of Brightness Preserving Dynamic Histogram
Equalization (BPDHE) having more brightness preserving capability with less computational …

Tone-mapping is a crucial step in the task towards displaying high dynamic range (HDR)
images on standard displays. Given the number of possible ways to tone-map such images …

Contrast enhancement of an image can be performed by using a simple histogram
equalisation (HE) technique. However, there are some drawbacks of HE like immense …

Monitoring bleaching provides an indication of coral reef degradation and is thus a reliable
tool for coral reef health assessment. Underwater photography of coral colonies integrated …

Coal mine safety monitoring technology has always been an important part of the mining
process. Underground video monitoring is an important means to ensure the safety of coal …

For many years different objective Image Quality Metrics (IQMs) have been introduced with
the goal of modeling the perceptual quality scores given by observers. While these IQMs …

Different wavelengths of light may undergo changes in underwater environment resulting in
altered images. For example, the presence of floating particles causes underwater images to …

Robust quantization watermarking with perceptual JND model has made a great success for
image copyright protection. Generally, either restores each color channel separately or …

There always exists subjective and objective color differences between digital wood grain
and real wood grain, making it difficult to replicate the color of natural timber. Therefore, we …
