Active origin method for affine matching

摘要

An active origin-based affine matching method was proposed in this paper. The basic idea is, the origin which has two adjustable parameters on the affine coordinate frame and the affine coordinate frame are both active. So the affine transformation between the model affine coordinate frame and the image affine coordinate frame has two adjustable parameters which will be applied to affine matching. Theoretical analysis and experiments demonstrated the proposed method being better than the conventional method.
