基于相似度匹配比的视觉跟踪

Visual Tracking with Similarity Matching Ratio

Purdue University(普渡大学)

Aysegul Dundar, Jonghoon Jin, Eugenio Culurciello

摘要:

提出了一种新的视觉跟踪方法:相似匹配比(SMR)。传统的跟踪方法是最小化模板和帧中的补丁之间的差异的一些措施。这种方法容易受到离群值和剧烈的外观变化的影响,一项广泛的研究正在集中于使这种方法对它们更宽容。然而,这往往会导致更长的,纠正算法不解决原来的问题。本文提出了一种新的方法来定义的跟踪问题,SMR,它变成了一个概率测度的差异。只有低于阈值的像素差异才对决定匹配进行计数,其余的都被忽略。这种方法使得SMR跟踪器对异常值和显著改变外观的点具有鲁棒性。SMR跟踪器在具有挑战性的视频序列上进行了测试,并实现了最先进的性能。

英文摘要:

This paper presents a novel approach to visual tracking: Similarity Matching Ratio (SMR). The traditional approach of tracking is minimizing some measures of the difference between the template and a patch from the frame. This approach is vulnerable to outliers and drastic appearance changes and an extensive study is focusing on making the approach more tolerant to them. However, this often results in longer, corrective algo- rithms which do not solve the original problem. This paper proposes a novel approach to the definition of the tracking problems, SMR, which turns the differences into a probability measure. Only pixel differences below a threshold count towards deciding the match, the rest are ignored. This approach makes the SMR tracker robust to outliers and points that dramaticaly change appearance. The SMR tracker is tested on challenging video sequences and achieved state-of-the-art performance.
