Signal Detection and Estimation 关于信号检测与估计的一本英文电子书，本书首先介绍了一些信号的随机过程，然后详细地介绍了一些信号检测和估计的方法。很好的一本外文书，大家一起分享。(Signal Detection and Estimation。This book is primarily designed for the study of statistical signal detection andparameter estimation. In the first,it present concepts on probability and random variables. Then,it present Statistical Decision Theory，Parameter Estimation.It is really a good book,share with all of you.)

这种方法一方面将像素的灰度值分散，可以分辨图象中比较细节的内容；另一方面，将图 象的灰度变化控制在一定范围之内，抑制了噪声的产生，较大程度上地保留了原始图象的亮度．(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)
