histogram-equalized image 直方图均衡化图像
Third, the gray-level histogram of image is equalized in order to reduce the influence of uneven light to the gray-level image.
第三步，为了减轻光线不均匀对灰度图像造成的影响，对产品图像进行灰度直方图均衡；
According to the characters of the images, the algorithm separated image into several regions by K-means clustering algorithm, and each region is equalized respectively within their gray levels.
该算法基于图像的特点，利用K均值聚类算法将图像分成几个灰度区间，然后再分别进行均衡化。
At first, the image background is suppressed by setting a threshold. Then, both gray density and gray interval of the histogram are equalized.
该算法首先通过设置平台阈值对背景的增强进行抑制，然后将直方图在灰度密度和灰度间距两个方向进行均衡处理。
