| Abstract: | At present,the illumination change is one of the difficulties in the recognition preprocessing.Classical light elimination pre-processing algorithms,including image enhancement (histogram equalization,gamma transform,and logarithmic transform),illumination invariant extraction (eigenface and quotient image),Retinex algorithm and logarithmic transformation and the improved algorithms are analyzed and summarized.Finally the future trend of light elimination research is pointed out. |
