这个是广义高斯分布随机数产生程序，它可以用做广义高斯分布形状参数的估计，以及用在图像处理，独立成分分析，信号处理，数字水印等方面。(This is the random numbers about the generalized Gaussian distribution.It can be used in image processing, ICA, signal processing,digital watermark and so on.)

本程序实现了两种误差扩散算法，分别用Sierra扩散滤波器和stenenson扩散滤波器，实现了比Floy_stein更好的误差扩散半色调效果。(This procedure implements two error diffusion algorithm, respectively Sierra diffusion filters and stenenson diffusion filter, to achieve better than Floy_stein error diffusion halftone effects.)

最优波束形成技术研究及硬件实现，适用于雷达和声呐方面(Optimal Beamforming technology research and hardware for radar and sonar terms)

（1）计算图像中每个像素点的LBP模式(等价模式,或者旋转不变+等价模式)。 （2）然后计算每个cell的LBP特征值直方图，然后对该直方图进行归一化处理(每个cell中，对于每个bin,h[i]/=sum,sum就是一副图像中所有等价类的个数)。 （3）最后将得到的每个cell的统计直方图进行连接成为一个特征向量，也就是整幅图的LBP纹理特征向量； 然后便可利用SVM或者其他机器学习算法进行分类识别了。((1) calculate the LBP pattern of each pixel in the image (equivalent mode, or rotation invariant + equivalent mode). (2) then the LBP eigenvalue histogram of each cell is calculated, and then the histogram is normalized (for each cell, for each bin, h[i]/=sum, sum is the number of all the equivalent classes in a pair of images). (3) finally, the statistical histogram of each cell is connected into a feature vector, that is, the LBP texture feature vector of the whole picture. Then, SVM or other machine learning algorithms can be used for classification and recognition.)

说明：  利用马尔可夫模型检测分割图像，获得MAP准则下的图像分割结果(??????????í ?? ?? ?? ?? ò?? ?? ???? ?? ì ?? ?? ?? ?? ???? ?? ???? ?? ?? ????μ??MAP × ?? ??ò????μ???? ?? ???? ?? ?? ?? ?? á ?? ??)

能完成钢筋数数，图像分割，直线检测，边缘检测，很好用。(Can finish the reinforcing bar counting, image segmentation, straight line detection, edge detection and works well.)

运用超像素分割算法对图像进行预分割，再利用dbscan聚类算法进行聚类最终实现图像分割。(The use of ultra-pixel segmentation algorithm for image pre-segmentation, reuse dbscan clustering algorithm to cluster the final image segmentation.)

说明：  可以读取输出浮点型、整型、复数型影像，对于遥感专业的所有影像读入输出MATLAB中有很大帮助。采用振幅离差阈值提取PS点(Can read floating-point, integer, and complex type of image, for all remote sensing professional images into the MATLAB will be very helpful)
