Abstract: The algorithm of image change detection was researched, and a novel unsupervised change detection technique was proposed. First, the optimal plane threshold and the optimal plane direction are searched by using improved 1D maximal entropy principle based on the 3D histogram clustering characteristic of different image. Then the segmentation plane is established to segment the 3D histogram into changed cluster and unchanged cluster. Finally, the changed pixels and unchanged pixels in different image are identified according to the segmentation of 3D histogram. The theoretical analysis and experiment results confirm the effectiveness of the proposed method.

Key words: change detection, 3D histogram, clustering characteristic
