利用稀疏表示进行图像去噪时，需要生成两种学习字典，该源码比较了生成的两种字典的优劣(Denoising sparse representation, it is necessary to generate two learning dictionary, which compares the generated source code of the merits of two dictionary)

图像质量评价，熵、平均梯度、边缘强度、方差等(Image quality evaluation, entropy, average gradient, edge strength, variance, etc.)

很好用的三维重建软件，VisualSFM软件允许上传一系列图像，它从这些图像中找到每一个图像的特定特征，利用这些特征信息重建出3D模型的稀疏点云，而后还可进行稠密点云重建。(The VisualSFM software, a good 3D reconstruction software, allows uploading a series of images. It finds the specific features of each image from these images, and USES these feature information to reconstruct the sparse point cloud of the 3D model, and then it can reconstruct the dense point cloud.)

说明：  这是我编写的关于计算机视觉中的一种重要的变换---射影变换的matlab源代码，希望对您有用。(This is what I prepared on computer vision in an important transformation of the projective transformation--- matlab source code, I hope useful for you.)

说明：  血管骨架提取文件。冠脉血管树重建冠状动脉造影图像的三维重建是一个复杂的过程 主要包括血管骨架提取与表达、血管段匹配、骨架点匹配、三维骨架重建、表面重建等步骤。(Extraction file of vascular skeleton. Three dimensional reconstruction of coronary angiography image is a complex process, which mainly includes the extraction and expression of vascular skeleton, vascular segment matching, skeleton point matching, 3D skeleton reconstruction, surface reconstruction and so on.)
