[W,L,q]=huffman(P) 为huffman编码函数 P为信源的概率矢量，W为编码返回的码字 L为编码返回的平均码字长度，q为编码效率 ">

由于显卡或者显示器的原因会出现实际输出的图像在亮度上有偏差，而Gamma曲线矫正就是通过一定的方法来矫正图像的这种偏差的方法.(Or because of the graphics display image will appear in the actual brightness of the output deviation, the Gamma correction curve is corrected by a certain method to the method of this bias image.)
