An algorithm to optimize coherence of motion vector in electric image stabilizing
Lei Xuan-hua · Journal of Naval University of Engineering · 2004
The block matching algorithm based on MAD (mean absolute difference) is extensively used in the motion estimation. In order to eliminate the inherent shortcomings of the classical block matching algorithm, quad tree--a size-variable block matching technique is proposed to optimize the coherence of motion vectors. Also this algorithm is compared with the other variable block matching methods. The experimental results show that this algorithm may produce reliable and coherent motion vectors.
