The key of block matching based on multi-bit-plane is how to accurately select bit-planes which contain abundant information, to ensure matching precision. In accordance with the characteristics of aerial video images and through taking a large number of experiments and data statistics a new algorithm that bit-planes are selected based on peak-value distribution of the histogram is proposed in this paper. Firstly, the paper introduces the relationship between the peak-value distribution and the information contained by bit-planes. Secondly the paper introduces the method to select bit-planes by analyzing the peak-value distribution. Finally two bit-planes containing abundant information are selected, at which small diamond search and big diamond search is performed respectively. Experiments show that bit-planes containing abundant information can be determined with the algorithm for different video, and the matching precision is guaranteed.
