DSSS matlab program to calculate DSSS

一个详细的matlab图像处理教学, 是某重点大学的课件 仅供参考(A detailed matlab image processing instruction, a key university courseware)

convolution using over add method

matlab中调用imhist函数来求图像的灰度直方图分布的方法，下载使用的话，只需要选择图像并改变改动图像的路径即可(imhist in Matlab)

First optimal threshold is calculated. after that we get a pfa value. then plot snr vs pd

本书重点介绍了在MATLAB环境下应用Maple强大的计算功能解决数值科学计算问题(the book highlights of the MATLAB environment Maple powerful computing capabilities to solve numerical problems in scientific computing)

说明：  老外编的标准pso算法的matlab工具箱(foreigners series of the PSO algorithm standard Matlab Toolbox)

Accurate smoothing of triangulated patch mesh

文中的方法是把图像分块，小波分解得到低频分量、高频分量，然后计算每一块的对比度，把图像块划分为清晰块、模糊块，把清晰块和模糊块相邻的区域定义为边界区域，融合时，直接选取清晰块作为融合后的相应块，对于边界区域，在小波分解的基础上采用基于对比度的像素选取的方法进行处理。(Paper, the method is to image segmentation, wavelet decomposition are low frequency, high frequency components, then calculate the contrast of each piece, the image block is divided into clear blocks, fuzzy block, to clear blocks and fuzzy block is defined as the border region adjacent to area, integration time, a clear block directly select the corresponding block as a fusion, for the border region, the wavelet decomposition on the basis of the pixel-based contrast method selected for processing.)
