具有位置信息的直方图测量图像增强方法

针对测量图像高噪声低对比度的特点,提出了一种具有位置信息的直方图均衡增强算法。将像素位置信息加入到标准直方图中,对图像进行灰度均衡处理,对背景和噪声进行适当抑制,对目标细节进行适当放大,从而克服了标准直方图均衡化增强时产生灰度合并的缺点。相对标准直方图的均衡算法,本文算法能够在增强图像整体效果的同时较好地保持图像的细节。

A Histogram Enhancement Method for Image Measuring with Location Information

For measuring high noise and low contrast image features,an algorithm of location information with histogram equalization enhancement is presented.The pixel location information will be added to the standard histogram equalization of image gray scale.It’s a way of appropriate to the background and appropriate details on the target amplification to overcome the shortcoming of gray merge cause by the standard histograms equalization enhancement.Compared with the standard histogram equalization,the algorithm can make the enhancement for measuring effective and maintain the image details better.
