Aiming at solving the problem of blurry details in the image sequence interpolation methods,this paper proposes a region-guided interpolation algorithm.The attention region calculation method is proposed according to the space and temporal characteristics of image sequences.The region interpolation mode is constructed and the details of the original image sequence can be maintained,so as to achieve high quality interpolation for the obtained attention regions.The detail enhancement method based on guide filter is proposed and it can improve further the definitions of attention regions,so the high resolution image sequences in accord with visual perception can be acquired.Experimental results show that,in the cases of different interpolation factors,compared with image signature detection algorithm and global contrast detection algorithm,the proposed algorithm achieves better visual effects and higher objective index values.
