摘要
图像的灰度级变换增强是图像增强处理技术中一种直接的基于空间域的处理方法。主要研究了将灰度图像的灰度级数用直方图来表示,在MATLAB平台中,通过编程研究了直方图均衡化和直方图规定化算法,使直方图分布均匀,达到图像的增强。
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, research- es the equalization and speeifieation algorithm of histogram, which makes the histogram homoge- neous distribute and enchances the image.
