实现函数imdilate的膨胀效果，自己编写的matlab函数实现。

数学形态学利里面的灰度腐蚀运算，自己看书写的，通过MATLAB仿真，和标准算法相同。-Lee inside the gray-scale mathematical morphology erosion operation, that looks at writing, through the MATLAB simulation, and standards for the same algorithm

Binary erosion and dilation, with fast iterative calls. For any structuring element other than square or disk this function is way faster than imerode.m and imdilate.m (more than an order of magnitude). It s also handy when you don t have the M
