An algorithm of SAR image denoising in nonsubsampled contourlet transform (NSCT) domain based on maximum a posteriori (MAP) and non-local (NL) restriction is proposed.

After denoising, a series of operations, binarization, skeleton extraction, fringe order assignation and interpolation, were implemented and the three-dimension phase map was obtained.

对滤波后的条纹图进一步采取二值化、骨架线提取、条纹级数标定、插值一系列操作，得到物体的三维相位信息。
