A gray-level image is decomposed into a 3-D image sequences by sub-sample of zigzag scan which are transformed using 3-D SWT.
首先，通过之字扫描把灰度图像分解为3维的图像序列，然后使用3-D SWT变换这些图像序列。
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；
The whole process is the morphology processing based on the gray-level image and binary mask, and is simple and easy to implement.
整个过程基本是对灰度图像和二值模板的形态处理，简单易行。
