直方图均衡化即归一化matlab程序，编写的目的也是为了模式识别处理样本。-Histogram equalization matlab that the normalization process, the preparation was also intended to deal with sample pattern recognition.

HISTOGRAMS Files fitt_distribution - The function fitts a predefined distribution to the histogram of an image. histtruncate - The function truncates the ends of an image histogram. rank_normalization - The function performs rank normal

这是一系列通过灰度映射、伽马调整、形态学变换、灰度直方图标准化等等方法来对图像细节进行增强的图像预处理matlab代码-Through a series of gray-scale map, gamma adjustment, morphological transformation, details in an image grayscale histogram normalization and so on ways to enhance the image preprocessing of
