该算法实现了通过霍夫变换提取直线和圆，希望对大家有帮助(This algorithm can extract line and circle through hough conversion.)

冲击噪声识别和消除的新算法，可以消除高达95 的冲击噪声，可用于毫米波成像等高脉冲噪声的恶劣环境(A novelt impulse noise removal algorithm which can work under the circumustance that the noise ratio reaches to 95 . )

用C++实现的对数变换达到图像增强效果，代码亲测可用(Logarithmic transformation realized by C++ achieves image enhancement effect, and code pro-test is available.)

这些代码主要是IDL语言源码，主要功能：初始化ENVI,定标,大气校正,融合,镶嵌,裁剪,分类(监督+非监督),面向对象特征提取,结束ENVI(These codes are mainly IDL language source code, the main functions: initialization, ENVI, calibration, atmospheric correction, fusion, mosaic, cutting, classification (supervision + non supervision), object oriented feature extraction, ending ENVI)

对图像进行平滑处理，能够很好的去除噪声的干扰，锐化图像能得到很好的效果(Of image smoothing, noise removal can be a good interference, sharpening an image can get very good results)

SSIM是衡量图像质量的另一个标准，比PSNR略好。此为计算图像SSIM的代码(SSIM is another measure of image quality, slightly better than PSNR. The code is to calculate SSIM.)

说明：  这是基于Camshift的目标跟踪code，编程语言为matlab。下载解压后可以直接运行。(This is the target tracking code based on CAMSHIFT, and the programming language is matlab. After downloading and decompressing, you can run it directly.)

基于角点信息和透视变换的图像镶嵌 matlab ()

对理想的心音信号加入噪声，仿真成实际带噪声的心音信号，然后对其进行维纳滤波程序(The ideal heart sound signal added noise, simulation into actual heart sounds with noise signal, and then its Wiener filtering program)

通过点云数据的格网化，建立格网分块索引，这是一种有效的点云数据存储方式。( Through the point cloud data grid , the establishment of a grid block index, which is a valid point cloud data storage. )
