基于环形颜色直方图的图像检索算发，比传统方法好用的多(Annular color histogram-based image retrieval count hair, easy to use than the more traditional methods)

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.)

分三种类型实现分水岭算法：一般分水岭分割、使用梯度的两次分水岭分割、使用梯度加掩模的三次分水岭算法(Realize three types of sub-watershed algorithm: a general watershed segmentation, the use of two gradient watershed segmentation, the use of gradient mask plus three watershed algorithm)

说明：  高斯投影正反算，将大地坐标转换为平面直角坐标系的坐标。(Positive and negative Gauss projection operator, the geodetic coordinates into Cartesian coordinates the coordinates.)

说明：  快速将图片裁剪为电脑壁纸和ipad壁纸尺寸，带预览(To cut pictures as PC or Ipad size conveniently)

计算四个方向的灰度共生矩阵，将其作为纹理特征，是一种纹理特征提取算法。(Calculation of the four directions of Gray Level Co-occurrence matrix as texture features, is a kind of texture feature extraction algorithm.)

对图像进行伽马校正，可以有效提升图像 亮度和对比度，低于低照度图像现在小于1的参数，对于高亮度的图像选择大于1的参数可以有效调节图像亮度。(Gamma correction can effectively improve the brightness and contrast of the image. The parameters lower than the low illumination image are less than 1. For the high brightness image, the selection of parameters greater than 1 can effectively adjust the brightness of the image.)

P_M正则化图像滤波的一个实验例子，包含程序和实验结果还有实验报告(Tikhonov P_M image filtering example of an experiment, including the procedures and experimental results are experimental report)

对图像稀疏编码和字典学习有个大致的了解，以及当前的研究现状(Sparse Coding and Dictionary)

基于自适应的区域选择和自适应的正则化得图像去模糊和超分辨处理，试过可以用(Based adaptive region selection and adaptive regularization was image deblurring and super-resolution processing)
