We propose a novel grayness index for finding gray pixels and demonstrate its effectiveness
and efficiency in illumination estimation. The grayness index, GI in short, is derived using the …

Multi-illuminant-based color constancy (MCC) is quite a challenging task. In this paper, we
proposed a novel model motivated by the bottom-up and top-down mechanisms of human …

Color constancy is the capability to observe the true color of a scene from its image
regardless of the scene's illuminant. It is a significant part of the digital image processing …

Achieving color constancy is an important part of image preprocessing pipeline of
contemporary digital cameras. Its goal is to eliminate the influence of the illumination color …

Digital camera sensors are designed to record all incident light from a captured scene, but
they are unable to distinguish between the colour of the light source and the true colour of …

Contrast is subject to dramatic changes across the visual field, depending on the source of
light and scene configurations. Hence, the human visual system has evolved to be more …

As a novel method eliminating chromatic aberration on objects, computational color
constancy has becoming a fundamental prerequisite for many computer vision applications …

Malaria is an extensively prevalent blood infection, the most severe and widespread
parasitic disease that stirring millions of people in the world. Currently, microscopy diagnosis …

Automatically describing digital images consists in extracting information that meaningfully
represents the depicted elements and their attributes. The specific concept of" meaningful" …
