Description: 基于MVDR算法，计算两个信号的相关性的函数。-This program computes the coherence function between 2 signals
x1 and x2 with the MVDR method.
This algorithm is based on the paper by the same authors:
J. Benesty, J. Chen, and Y. Huang, "A generalized MVDR spectrum,"
IEEE Signal Processing letters, vol. 12, pp. 827-830, Dec. 2005.
x1, first signal vector of length n
x2, second signal vector of length n
L is the length of MVDR filter or window length
K is the resolution (the higher K, the better the resolution) Platform: |

Description: Image Edge Enhancing Coherence Filter Toolbox，各向异性非线性扩散滤波器-This toolbox will perform Anisotropic Non-Linear Diffusion filtering on a 2D gray/color or 3D image. This filtering will reduce the image noise while preserving the region edges, and also enhancing the edges by smoothing along them.
This is one of the more advanced image enhancement methods available, and also contains HDCS from october 2009. The result looks like an artist painted the image, with clear brush strokes along the image edges and ridges, see screen-shot.
