视频检索，图像识别等方面的内容，用于matlab(Video retrieval, image recognition and other aspects)

禁忌搜索（Tabu search）是局部邻域搜索算法的推广，Fred Glover在1986年提出这个概念，进而形成一套完整算法。 (Tabu search (Tabu search) is a local neighborhood search algorithm for the promotion, Fred Glover in 1986, proposed this idea, thus forming a complete set of algorithms.)

High accuracy optical flow using a theory for warping(The files optical_flow_brox.m and optical_flow_sand.m are the files you need to run. optical_flow_brox.m implements the traditional algorithm. Just replace the first lines where images are read, with your image, and start the process. optical_flow_sand.m implements a variant presented in CVPR 2006. Again just replace the lines "img1 = imread( ... )" and "img2 = imread( ... )" with your images and the rest is automatic. The variable num_levels controls the number of images in the laplacian pyramid to be constructed. Change it to suit your convenience.)

参数可控的分数阶傅里叶变换，可通过改变参数来进行傅里叶变换(Parameters controllable fractional Fourier transform, by changing the parameters to the Fourier transform)

This is the image segmentation code. It uses built in fuction fcm to perform the image segmentation. It partition the images into seven clusters.
