Abstract:
In this paper, a novel framework for image retargeting based on two-directional non-uniform scaling with region-aware texture enhancement is proposed. First, the importance map is estimated via saliency and depth information from an input image. Then, two-directional scaling functions are derived from importance map by 1D projection onto horizontal and vertical axis according to estimated scaling portion which controls the resizing rate of each direction. Finally, the target image is generated by two-directional non-uniform scaling with region-aware guidance map. Experimental results validate the proposed framework can achieve content-preserving and visually pleasing results compared to the conventional methods.
