基于概率密度的兴趣点检测算法

  总被引：1，自引：0，他引：1

针对基于亮度兴趣点检测算法存在对纹理敏感和兴趣点分布不均匀(集中于高对比度区域)问题, 提出了一种新颖的基于概率密度的兴趣点检测算法. 该算法在经典的Harris角点检测算法基础上, 利用亮度的概率密度梯度代替亮度的梯度构建二阶矩矩阵, 进行兴趣点检测. 与基于亮度的Harris… …   相似文献

Onk-positive satisfiability problem

下载全文  

An algorithm for solving the satisfiability problem is presented. It is proved that this algorithm solves 2-SAT and Horn-SAT in linear time andk-positive SAT (in which every clause contains at mostk positive literals) in timeO(|F|·ξ _n ^k ), where |F| is the length of inputF, n is the number of atoms occurring inF, and ξ _k is the greatest real number satisfying the equation . Compared with previous results, this nontrivial upper bound on time complexity could only be obtained fork-SAT, which is a subproblem ofk-positive SAT.
