国外的潮流计算程序 MATLAB矩阵思想很重要 我有些糊涂 希望大家共同讨论(Program abroad, the trend of thought is very important MATLAB matrix confused me some hope that we discuss)

用快速傅里叶变换实现图像融合，将一个人脸上的妆融合到另一个人脸上(With fast Fu Liye transform image fusion, a person will face makeup into another face.)

自适应中值滤波与中值滤波算法的比较，说明自适应中值滤波效果好。(Adaptive median filter and median filtering algorithm comparing the adaptive median filter shows good results.)

图形图像的处理 基于加权的融合方法MATLAB程序设计(Graphic image processing method based on weighted fusion MATLAB programming)

里面是小波分析的实现方法，还有数学介绍。数字信号处理上机实验答案(第三版).docx的电子版(There is a wavelet analysis method, as well as mathematical description. Digital signal processing on the experimental answer (third edition). Electronic version of docx)

卡尔曼滤波的基础上简要介绍了和处理代码。过程通过随机噪音过滤掉，以获取原始信号。(Kalman filter based on a brief introduction and processing code. Process through the filter out random noise to obtain the original signal.)

说明：  自编二值算术编码算法的matlab演示。从text.txt读取信息，编码过程及结果由matlab图形演示(binary arithmetic coding algorithm matlab demo. Reading information from Text.txt and the encoding process and the results are showed by the matlab graphics demo step by step.)
