An improved path-based image interpolation method
Yue Chen, Liu Liu, Bo Yan · 2011
Image interpolation, the problem of producing a sequence of intermediate frames between two input images, is of significant interest. The application of image interpolation is numerous, from animation of still images to temporal interpolation. In this paper, not only do we achieve implementing the original path-based interpolation method, but we also induce optical flow as the innovate point of improvement. We use optical flow to decide the direction of path, to constraint the path length and to maintain the global path coherency, which improves the efficiency significantly. The improved path-based method obtains considerable improvements.
