一个基于内容的图像检索系统，对搞图像检索的应该会有所帮助！！！(A content-based image retrieval system, engage in retrieval should help! ! !)

[X,Y,Z] = k_clique(k,A) Inputs: k - clique size A - adjacency matrix Outputs: X - detected communities Y - all cliques (i.e. complete subgraphs that are not parts of larger complete subgraphs) Z - k-clique matrix(k-clique algorithm as defined in the paper Uncovering the overlapping community structure of complex networks in nature and society - G. Palla, I. Derényi, I. Farkas, and T. Vicsek- Nature 435, 814–818 (2005))
