Since the widespread availability of cameras black-and-white (BW) photography has been a
popular choice for artistic and aesthetic expression. It highlights the main subject in varying …

Converting a color image into a grayscale image is a complex problem that is based on
preserving color contrast, sharpness, and luminance. In this paper, a novel image …

Pansharpening is an important fusion method in remote sensing image processing, aiming
at obtaining a multispectral image with high spatial resolution by fusing a multispectral …

Image decolorization is widely used in single-channel image processing, black-and-white
printing, etc. Decolorization aims to generate a perceptually satisfactory gray image that …

It is challenging to convert a hazy color image into a gray-scale image because the color
contrast field of a hazy image is distorted. In this paper, a novel decolorization algorithm is …

The purpose of decolorization is to convert a color image into a grayscale image while
maintaining the contrast and structural characteristics of the original color image as much as …

Image decolorization is used to realize the color-to-gray conversion, which is widely used in
black-and-white printing, digital-ink display, photo stylization, etc. Image contrast fidelity …

Invertible color-to-grayscale conversion is a research issue in grayscale image colorization,
which is a complex problem resulting from information loss. This paper presents an …

Color-to-gray conversion is popularly used in black and white printing and other image
processing tasks. In this paper, we propose an adaptive linear weighting algorithm based on …
