高阶谱分析3，适用于阵列信号处理、雷达信号处理等(。-High-order spectral analysis toolbox for array signal processing, radar signal processing.)

The proposed approach satisfies the integrability condition and does not need any boundary condition assumptio-ns, we have designed a stand-alone, flexible Matlab implementation that enables to evaluation the proposed approach. The experiments on real images show the approaches ability to reconstruction the surface from SFS.
