仿射变换法求深度信息，目前最好的方法

function [Z,D11,D12,D22] = diffusion_kernel_function(gx,gy,im)

gx,gy 为x,y方向偏导数 Z 为恢复出来的是深度信息。

函数适应于从 图像法相信息恢复高度信息-Affine transformation method the depth of information, is currently the best way to function [Z, D11, D12, D22] = diffusion_kernel_function (gx, gy, im) gx, gy for x, y direction of the partial derivative of Z is out to restore the depth of information. Function adapted from the image information to resume a high degree of information law
