摘要： 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

摘要： 1.MingmingCheng,GlobalContrastbasedSalientRegionDetection,CVPR20111)HC：基于直方图对比度的方法，每一个像素的显著性值是由它与图像中所有其他像素的颜色差异来确定，得到全分辨率显著性图像；2)RC：基于局部对比度的方法，先将图像分割成小区域，采用的分割方法是基于图的分割，基本分割思想是将每个像素点作为无向图的顶点，两个像素点之间的不相似度作为边的权重，要求连接相同区域内的两个顶点的边的最大权重要小于连接不同区域的顶点的边的最小权重，在迭代过程中进行顶点归纳与区域合并，具体参见论文Efficientgraph-basedimages 阅读全文
