On a basis of Retinex and YIQ color space, a new approach of color image enhancement is presented in this paper. The original image in the RGB color space is converted to the YIQ color space, and the multi-scale Retinex (MSR) algorithm is introduced to ...
Digital imaging is widely applied in medical, surveillance, machine vision, and other fields. Occasionally, limited light sources during image acquisition process cause non-uniform illumination and low contrast images. Non-uniform illumination and low-...
The histogram equalization (HE) is a technique developed for image contrast enhancement of grayscale images. For RGB (Red, Green, Blue) color images, the HE is usually applied in the color channels separately; due to correlation between the color ...
