仿射投影符号算法是仿射投影算法和符号算法的组合算法，具有良好的抗冲击噪声的能力。(Affine projection algorithm is a combination algorithm symbol affine projection algorithms and symbolic algorithms, have good impact noise capabilities.)

高斯金字塔-对图像进行高斯金字塔表示，先进行高斯滤波，然后逐层抽样(Gaussian Pyramid- Gaussian pyramid of images, said first Gaussian filter, and then layer-by-layer sample)

读入人脸图像，根据图像的水平，垂直灰度积分情况，将人眼范围取出，背景可以较复杂。(Reading into the human face image, according to the image of horizontal, vertical gray points, which will remove the scope of the human eye, the background can be more complicated.)

用于实现基于压缩感知在傅里叶系数域上的图像融合(For image fusion based on compressed sensing in the domain of Fourier coefficients)

多种图像增强方法，效果都挺好的的。包括dct，灰度变换，直方图均匀化，图像锐化(variety of image enhancement methods, the results are very good. Including Extra, the gray-scale transformation, histogram equalization, image sharpening, etc.)
