In addition, removing multiples, refractions and primaries with K-L transformation can avoid removing the useful waves together with interfering waves and keep the useful shallow seismic information.
利用K - L变换对浅层多次波、折射波、直达波的压制，可避免手工切除对浅层有效信息和干扰信息一刀切的弊端，保存了浅层有效信息。
Firstly, it turns the original image into CIELAB color space, then computes histograms of L and a separately.
该方法首先将原始图像变换到CIELAB颜色空间，然后对所得图像的L和a分量分别进行直方图统计。
Please stop changing the google logo so much l like the original one.
