摘要	A new image stabilization algorithm based on the characteristic peak of projection matching was proposed to improve the real-time characteristics of gray projection image stabilization method. Firstly, the reference frame and the current frame were divided into several sub image blocks, and the horizontal projection and vertical projection of each sub image block were calculated according to the projection calculation formula. Then, the horizontal and vertical position differences of the corresponding sub blocks' maximal projection characteristic peaks were calculated as motion vectors, and the motion vectors were corrected according to the motion vector variance ratio between frame and frame. Finally, the global motion vectors were derived based on the sub motion vectors. The proposed algorithm based on the characteristic peak of projection matching was used in a multi-spectral imager and obtained results were compared with that of the traditional gray projection image stabilization method. The experimental results show that new algorithm has saved nearly 20% time as compared with that of the traditional one for 1024 pixel1024 pixel resolution image sequence and the (-60, 60) regions of search. It does not have complex match processing that traditional method has to research the image projection area one by one, and can offer good real-time performance and stabilization effect. , 2015, Chinese Academy of Sciences.
