Fast template matching method for rotation invariance
Jiaojun Li · Jisuanji gongcheng yu sheji · 2006
The computation of conventional cross-correlation type algorithms is expensive.Furthermore,when the template rotate relative to the image,the amount of computation with conventional algorithms is larger.An algorithm for a rotation invariant template matching method based on the combination of the circle projection method and Zernike moments is researched.By making circle pro-jection,Image can be transformed to one dimension from two dimensions,thus computational complexity is reduced and fast coarse matching is also processed by cross-correlation measure.Then accurate template matching is performed only on the matching candidates using Zernike moments.
