用于去除背景，得到原图与背景相减的图像并二值化

分别采用RGB模型和HIS模型对图像imageLane.bmp进行锐化，并比较锐化的效果是否相同（两锐化后的图像相减）。-Using RGB model respectively for imageLane image and HIS model for sharpening, BMP, and compared the effect is the same sharpening (two sharpen the image subtraction).

俩个图像相减，得其差值图像,效果还不错，值得下载！-the cha of two map，it s very good.whatever,just to try.

输入一幅图像，用传统的算子方法进行检测与用形态学腐蚀之后使原图像与腐蚀后的图像相减得到图像边缘进行比较-The Mathematical Morphology Image Edge Detection Based on MATLAB
