Two novel semi-fragile watermarking algorithms respectively based on JPEG and JPEG2000 are proposed in this paper.

Finally, we proposed a semi-automatic target dividing method. The simulation results showed that we could get moving target by dividing and extracting features using the proposed algorithms.
Most of the existing semi-supervised clustering methods neglect the structural information of the data, while the few constraints available may degrade the performance of the algorithms.
