实现bmp位图的对比度拉伸，包含GUI界面，实测能用-Bmp bitmap contrast stretching, contains the GUI interface, measured can be used

该GUI比较简单，可以自由读取位图，并将其二进制，也可对其添加噪声；分割算法主要有边缘检测分割，及分水岭分割。-The GUI is simple, you can freely read the bitmap, and binary, its also add noise segmentation algorithms are mainly split edge detection, and watershed segmentation.
