1.AliBorji,LaurentItti,ExploitingLocalandGlobalPatchRaritiesforSaliencyDetection,CVPR20121)系统框架：2)算法思路：① 图像表示：本文通过1500张图像中，在各通道提取出的8*8的patch，学到了一个自然图像的字典。使用这个字典以及一系列的系数α就可以重组任何一个patch。各通道分别进行。因此，在学习了字典，并且使用Matlab中的LARS算法进行了稀疏编码系数α的估计之后，每个patch通过系数表示成一个矢量。② 显著度计算：在这些矢量上进行局部和全局显著度的计算。局部显著度为两个图像块系数向量在特 阅读全文
