小波阈值消噪程序，能量谱分析，希望能帮助大家(Wavelet threshold denoising procedures, energy spectrum analysis, we hope to help)

Frank-Wolfe算法 matlab(rank-Wolfe, matlab)

This file is written as if you are going to evaluate the error between a pair of images that are presently coded as RGB data. The initial calculation converts the RGB data to CIE XYZ data. The calculations are similar if your images are coded as CMYK, but you will need to convert from CMYK to XYZ instead of converting from RGB to XYZ.
