摘要: Corner detection algorithm is key to the image registration based on corner feature point. According brain magnetic resonance (MR) registration, this paper proposed a hybrid by combining Harris and Susan operators applied it into MR registration. Firstly, method extracts points using operators. Secondly, merges conducts weight computation two coefficients ω 1 2 . After that, can be chosen further. Through normalization relevance voting mechanism, final are further matched between reference needing Finally, Powell used transform obtained. The experimental results show that for obtain higher precision and.
