平滑去噪及均衡增强用于改善退化图像

APPLICATION OF IMAGE SMOOTHING AND HISTOGRAM MODIFICATION IN IMPROVING DEGRADED IMAGES

用图像平滑去噪、灰度级直方图均衡增强等空域处理技术改善退化图像,探讨了图像处理设备对(?)待处理对象的限制,以及空域处理技术对图像空间相关性和图像信源熵的影响等问题.给出了实验结果。

Some space domain techniques(SDTs)such as image smoothing and histogram modification had been applied to improve degraded images.It is discussed that,(1)the image processing system has limitation on the subjects and(2)the SDTs have influences on the correlation of images and cntropy of image sources.Experimental results had shown that,the above SDTs would increase the correlation and decrease the entropy.This will provide a possible method to pre-process images before coding.Experimental results are presented.
