Abstract:

In order to improve the perception ability of multimedia processing, a transcale interpolation model is proposed for the dynamic image sequences. Firstly, the visual attention regions are obtained by utilizing visual saliency detection from the viewpoint of users, so as to determine the outstanding regions of dynamic image sequences. Secondly, coherency sensitive hashing is adopted and high quality interpolation frames are generated when the time scale is changed. Finally, the energy function of the target images is defined, so the quality of visual attention regions could be improved when the resolution scale is changed. Experiments show that the proposed model achieves better interpolation results.

Key words: transcale, interpolation model, visual saliency detection, image sequences
