包括图像的预处理，多种阈值分割方法，边缘提取，形态学处理，RGB到灰度图象的转换等等，用于图像的常规处理-including image preprocessing, multiple threshold segmentation, edge detection, morphology, RGB images to gray scale conversion, and so on, for the conventional image processing

数字图像处理：如灰度变换、图像增强、图像滤波、图像二值化及图像分割等。程序可运行。-Digital Image Processing: gray-scale transformation, image enhancement, image filtering, image binarization and image segmentation. The program can be run.

二维图像分割，画出灰度图像和背景的分界线-Two-dimensional image segmentation, to draw the dividing line between gray-scale image and the background

This paper presents a new algorithm for partitioning a gray-level image into connected homogeneous regions. The novelty of this algorithm lies in the fact that, by constructing a minimum spanning tree representation of a gray-level image, it reduce
