论文:Person Re-identification based on nonlinear ranking with difference vectors
发表在:2014 information science
论文思路:
第一步:行人分割5块,分别提取30维度的HSV通道直方图特征,另外,从一个红框中,也就是行人身体中心部位再提取一个HSV直方图特征
第二步:根据样本对,构造正例和负例集合,将Rank问题转为排序问题
第三步:利用聚类方法对样本负例进行聚类,减少样本之间的不平衡问题
第四步:利用libsvm工具,选择RBF核进行分类,得到排序结果。
值得借鉴的思路在于:聚类的方法,降低样本间的不平衡问题。
