McCann's Retinex Enhancement Method Based on YUV for Space Station Image

In the space station, the hash and uneven illumination brings a significant challenge to the vision system, which is the precondition of monitoring, unattended operation and robot operation. This challenge is caused by the high dynamic range of light intensity and the light reflection of metal facilities. Aiming at this problem, Retinex algorithm was proposed to estimate the luminosity. Firstly, the structure and mechanism of human eyes are analyzed. Secondly, based on that, McCann's Retinex algorithm is used to enhanced the images. Finally, the original image is enhanced by merging the new brightness layer and the color layer. The experimental results show the validity of the proposed algorithm.
