说明：  1. 在GUI中，实现图像的阈值分割（交互式、迭代法）、区域生长。 2. 在GUI中，，实现二值图像的膨胀、腐蚀, 比较'结构元素类型为：square,line, diamond, disk等的区别。 3. 在GUI中，实现二值图像的开运算、闭运算。 4. 在GUI中，实现二值图像的形态学应用： 边界抽取 (boundary extraction) 区域填充 (region filling) 细化 (thinning) 粗化 (thickening) 骨架 (skeletons) 修剪 (pruning)
(1., in GUI, the image threshold segmentation (interactive, iterative), region growth is achieved. 2. in GUI, to achieve expansion and corrosion of two valued images, compare the types of structural elements: square, line, diamond, disk and so on. 3. in GUI, to achieve two valued images on the open, closed operations. 4. morphological applications of two valued images are implemented in GUI: Boundary extraction (boundary, extraction) Zone fill (region, filling) Refinement (thinning) Roughening (thickening) Skeleton (skeletons) Trim (pruning))
