Application of Retinex in Color Restoration of Image Enhancement to Night Image

Many monitoring and reconnaissance images are shot in night without auxiliary light, so those images are usually very dim and need enhancement processing which can be realized by Retinex with a good effect, but Retinex needs the color restoration. Based on the contrastive analysis on the RGB and the...

More Information
Summary:Many monitoring and reconnaissance images are shot in night without auxiliary light, so those images are usually very dim and need enhancement processing which can be realized by Retinex with a good effect, but Retinex needs the color restoration. Based on the contrastive analysis on the RGB and the HSI color space, the differences, advantages and disadvantages are compared considering the transformation of Retinex algorithm from the RGB to the HSI to construct the SSRHSI algorithm to obtain the new effect on the color restoration.
