最大熵直接迭代法,维纳滤波和盲恢复对水平方向匀速直线运动造成的模糊图像的恢复研究(Direct iterative maximum entropy method, Wiener filtering and blind restoration of the horizontal direction caused by uniform linear motion blurred image restoration)

说明：  对JPEG细粒度 图像质量评价的算法评估。SSIM的KLCC（肯德尔秩相关系数）。(Algorithmic evaluation of JPEG fine-grained image quality evaluation. KLCC (Kendall Rank Correlation Coefficient) of SSIM.)

最大最小距离算法matlab代码，注释比较详细(Maximum minimum distance algorithm matlab code)

该程序基于视频统计车流量。该算法通过识别出交通场景图像中复合车辆特征的像素，进行图像分割，并依据提取出来的特征来匹配前后两幅图像中的车辆，从而计算车流量。(The program is based on the video statistics vehicle traffic. The algorithm calculates the traffic volume by recognizing the pixels of the composite vehicle feature in the traffic scene image, segmenting the image, and matching the vehicles in the two images according to the extracted features.)

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.)

实现数字图像处理的直方图均衡化，将一幅灰度图像的频谱展示处理(histogram equalization)

说明：  图像的尺度不变特征特征点提取，快速提取图像的特征点(SIFT feature extraction of image)

大米大学(rice University)单像素相机的程序，简单易用。(Single-Pixel Camera Algorithm and MATLAB implement.)

输入一个带权无向图的顶点数、边数、各条边信息（两个顶点和权值），建立该图的邻接矩阵结构，输出该邻接矩阵。将上述无向图邻接矩阵转换为邻接表结构，输出该邻接表；根据该邻接表对无向图进行深度优先遍历序列和广度优先遍历序列，并输出遍历结果；用prim算法实现构造该带权无向图的最小生成树，并将该最小生成树的各条边信息输出。(Enter a weighted undirected graph with vertices, edges, each of the side information (two vertices and weights), the establishment of the adjacency matrix structure, the output of the adjacency matrix. The above undirected graph adjacency matrix into adjacency list structure, the output of the adjacency list according to the adjacency table undirected graph depth-first traversal sequence and breadth-first traversal sequence, and outputs through the results using prim algorithm construct the weighted undirected graph minimum spanning tree, and the minimum spanning tree information on respective sides of the output.)
