| 摘 要： | 针对区域立体匹配算法中匹配窗口自适应选择的难点,提出一种基于多尺度分析Nonsubsampled Contourlet变换(NSCT)的快速区域立体匹配新算法.首先介绍NSCT并对其时移不变性进行讨论.采用由粗到精的匹配策略和快速的SMP匹配代价函数降低运算量.实验结果表明,该算法具有很高准确率.

| Abstract: | One of the central problems in stereo matching is the selection of optimal window sizes for comparing image regions.This paper presents a fast and reliable multi-scale stereo matching algorithm based on the Nonsubsampled Contourelet Transform(NSCT),which is a fully shift-invariant,multi-scale,and multi-direction expansion that has better directional frequency localization.This method consists of multiple passes which compute stereo matches with a coarse-to-fine and sparse-to-dense paradigm.Then,we using a f... |
