主　　题：深海海底照明 非均匀照明效应 自适应滤波 

摘      要：The deep_sea floor images are acquired under non_uniform illumination,the effects of which bring up many difficulties for image *** paper compares three methods of removing non_uniform illumination *** effectiveness and robustness are evaluated on three test images with high_,moderate_ and low_density grains,*** results show that local filtering algorithm does not remove the non_uniform illumination effects *** image subtracting algorithm will lose some of the dynamic range of the original *** enhanced image stretching algorithm is the most effective one.
