LCA (Lobe Component Analysis) Lobe成分分析法，图像基元的特征检测算法。

柏松选择性对比度调整，该算法自动调整对比度，使得图像清晰度增强。需要fftw3.-Selective Contrast adjustment, Given an image, the algorithm modifies the gradient vector field of the image and finally it recovers the new image by solving the poisson equation using the Fast Fourier Transf
