Matlab源代码：利用有序抖动算法（Bayer矩阵D4和D8）生成二元图像；利用误差扩散算法（Floyd-Steinberg filter）生成二元图像。-Matlab code using the ordered dithring (Bayer D4 and D8 matrix) to generate the binary images Matlab code using the error diffusion algorithm (Floyd-Steinberg filter) to

通过arcgis采用D8算法得到的流向（flow direction），将产流进行汇流计算，汇流原理同arcgis中的flow accumulation。 可以通过对该代码修改完成水文模型的不同修改-D8 algorithm is obtained by using arcgis flow (flow direction), the production flow convergence calculation, convergence in principle with arcgis f
