Abstract: The transform enhancement of image grayscale is an direct image processing method based on spatial domain in image enchancing processing technology, using histogram to show gray series in gray image is researched. On matlab platform, through programming, researches the equalization and specification algorithm of histogram, which makes the histogram homogeneous distribute and enchances the image.

Key words: histogram, image spatial domain, image enhance
