基于ART算法的CT图像重建 刚找到的，不知能不能用(CT image reconstruction based on ART algorithm)

改进非极大抑制的CANNY算子检测代码，能够比原来的CANNY算子更准确(Improved CANNY operator detection code for non-maximal suppression can be more accurate than the original CANNY operator)

图像去噪，小波硬阈值滤波，sym4小波基函数(Image denoising and hard threshold wavelet filtering, sym4 wavelet basis function )

五种粒子滤波仿真，便于初学者学习粒子滤波算法(Five particle filter simulation, easy for beginners to learn particle filter)

尼康相机拍摄的原始数据RAW格式，matlab实现该类格式的读取，显示。便于计算机进行后续的处理。直接运行即可。(RaW format of raw data captured by Nikon camera, which is read and displayed by matlab. It is convenient for computer to carry out follow-up processing. It can run directly.)

图象特征提取的相位编组方法，欢迎各位同仁下载研究。(image feature extraction phase of organizational methods, and to welcome you download colleagues study.)

利用SSDA算法实现模板匹配的功能，该算法可快速有效地完成图像的匹配。(SSDA algorithm on template matching function, the algorithm can quickly and efficiently complete image matching.)

两个l1准则下的噪声干扰信号压缩感知重构举例，两个例子的稀疏矩阵均为DCT矩阵，而观测矩阵分别采用单位阵和随机矩阵，有详细的步骤和使用方法，适用于初步的学习压缩感知方法。(This programme supply two examples by Compressed sensing with l1 norm. The sparse matrix of two examples are all DCT matrix and the obsever matrix are unit matrix and random matrix respectively. We give the detailed usage and steps for the programme which is useful to the beginner.)

对Lena图先进行jpeg压缩，再对压缩后的图像分别进行小波软阈值去噪和非抽样硬阈值去噪，比较两种去噪方案，非抽样硬阈值有更好的效果。这是根据一篇外文文献来进行编程的，最后有图像对比结果。(According to the paper of OPTIMAL WAVELET THRESHOLDING FOR VARIOUS CODING SCHEMES ,I firstly compresse the Lena picture using the jpeg method ,then respectivly denoise it using the wavelet soft-thresholding method and the undecimated DWT hard-thresholding method.Comparing the two method ,we can find the undecimated DWT hard-thresholding have a better result.)

imnoise的M文件，对数字图像的加噪声非常有用处！(imnoise M-files, plus noise on digital images is very useful!)
