matlab实现国旗识别

用matlab实现光流法求物体的运动速度（根据相邻两帧之间的比较）(The optical flow method realized by matlab can be used to calculate the moving speed of objects.)

说明：  matching pursuit algrithmic

< 数字图像处理算法及应用>这本书的相关代码(Image Processing Algorithm and Practices is an important book in IP and AI. High-pass Filter is very normal and practical tool.)

说明：  通过编写IDL语言，实现使用IDL语言进行分区统计功能。(By writing IDL language, the function of partition statistics using IDL language is realized.)

说明：  用分水岭算法进行图像分割，借鉴形态学理论，将一幅图看成拓扑性地图，其中灰度值对应地形高度。(The watershed algorithm is used for image segmentation, and a map is regarded as a topological map, in which the gray value corresponds to the terrain height.)

使用echat 绘制的地图 百度地图api(Map drawn using echat baidu map api)

常用的三维点云数据，手的三维数据可以用MATLAB和PCL打开。(Common 3D point cloud data)

去除彩色图像中的阴影，以便于图像分割，物体识别以及跟踪(To remove the shadow of color images in order to facilitate the image segmentation, object recognition and tracking)

说明：  a）针对合成纹理图像（共有4 个合成纹理图像，见文件夹： Texture_mosaic_data）中每一个像素提取纹理特征向量； b）利用聚类技术（推荐用k‐均值聚类，可以从网上查找原码）对特征向 量空间中的点进行聚类，类别数可根据图像中的实际纹理类数确定。最后把类 属标签映射成图像形式显示（如下图，其中b、d、f、h 为相应的基准分割图像）。(A) for synthetic texture images (there are 4 synthetic texture images in total, see the folder: Texture feature vector is extracted from every pixel in texture; B) use clustering technology (K-means clustering is recommended, and the original code can be found on the Internet) to search the feature direction The number of categories can be determined according to the actual number of texture classes in the image. Last class The generic label is mapped to an image (as shown in the figure below, where B, D, F, h are the corresponding reference segmentation images).)

用拉普拉斯金字塔的方法，对两幅聚焦位置不同的图象进行融合处理，获得更清晰的图象。(Laplace pyramid, focusing on two different positions of the image fusion, more clearer picture.)
