Abstract: The Retinex algorithm for face image illuminationcompensation and color restoration is an effective one in the traditional imageenhancement algorithm under the condition of low illumination The traditionalMSRCR algorithm can still produce some problems such as low sharpness
blurreddetails and incomplete color after image processing Therefore
this paperproposes a compression expansion multiscale Retinex algorithm with colorrecoveryCMSRCR
which uses multicolor channel bending transformation functionand factor correction method to enhance and restore lowillumination face imagesThe results show that the CMSRCR algorithm can improve the sharpness
detailand color restoration of low illumination image
