This paper researched the problem about robust tracking of rotated objects in visual tracking
and proposed a swift matching exhaustive search algorithm based on Rotation Invariant Histogram-RIH.Firstly
it summarily reviewed the current histogram-based matching algorithms
and then proposed the rotation invariant histogram after detailedly analysis of rectangle template's invalidation when tracking rotated objects.RIH can precisely track an arbitrarily rotated object using only two circinal templates.It carries out the global optimal exhaustive search on the basis of the rotation invariability of circinal template and the efficiency of distributive histogram's computational complexity
and achieves the rotation-corrected tracking result using the relationship of the two circinal templates' location.Finally
a series of video sequences were tested
and the experimental results validate that the proposed algorithm is robust to track the arbitrary rotation objects with a low algorithm complexity.
