提出了一种新的基于小波包变换 和偏斜度的检测方法。该方法利用小波包对图像进行多尺度分解，解决了高频段分辨率低的问题； 并提出了一个基于偏斜度的高斯判别准则，用于对小波包分解系数进行高斯性检验，最终得到了 小目标的精确检测(The wavelet packets were applied to decompose the image into pyramid subbands at different scales and solve the problem of the higher frequencies having lower resolutions. Then a Gaussian measurement criterion based on skewness was proposed to test the Gaussian nature of the wavelet packet coefficients and finally the exact detection result was obtained. )

说明：  基于压缩感知思想的图像分块压缩与重构方法 考虑到大多数图像信号信息分布有差异, 编码端, 在对图像分块的基础上, 融合熵估计 和边缘检测方法计算各图像块的信息含量, 再从两个不同的角度进行分类采样: 依据信息量多少将图像块分为平滑、过渡和纹理3 类, 使用不同的采样率采样 依据信息量的分布特征, 采用不同的采样率分配策略进行采样. 在解码端, 根据不同类型的图像块构造不同的线性算子进行重构, 再运用改 进的迭代阈值算法去除块效应和噪声. 实验证明, 算法在提升图像重构质量的同时缩短了重构时间,并且对纹理边缘多的图像的重构效果较其他方法理想.(Considering that most information of the image signal difference distribution, the encoding side, in the right image sub-blocks based on the integration entropy estimation And edge detection method for calculating the information content of each image block, and two different angles classification sampling: The number of image blocks based on the amount of information into a smooth, transition and texture three classes, using different sampling rates based on the amount of information distribution characteristics, using different sampling sampling rate allocation strategy. in the decoding side, depending on the type of image blocks to construct different linear operator reconstructed, re-use change Iterative thresholding algorithm into blockiness and noise removal experiments show image reconstruction algorithm to enhance the quality while reducing reconfiguration time, and much of the texture edge image reconstruction results are satisfactory compared to other methods.)

本程序用来计算matlab中两点坐标之间的距离，坐标必须是经纬度，并表明所要计算的单位(This procedure used to calculate the matlab in the distance between two coordinates, latitude and longitude coordinates must be, and show that to calculate the unit)

matlab的GUI编程指导，对有需要做GUI界面的朋友可能会有帮助。(GUI programming in matlab guidance necessary to have friends to do GUI interface may be helpful.)

说明：  用于生成BCH码的生成多项式和最小多项式的malab代码，以及伴随式的计算表达式(BCH code used to generate the generation polynomial and minimal polynomial of malab code, as well as the calculation with the expression)
