Image retargeting through fusion of contour and region information

Image retargeting techniques aim to adapt images to the target screens with different sizes and aspect ratios.This has been one of the hot topics in multimedia research.Its key is to highlight important areas,keep continuity and avoid twists.This paper presents a novel image retargeting method.Based on human visual attention,energy map and sensitivity energy maps are calculated by salient region features and weighted contour features,respectively.Thus,in the process of scaling these low-energy lines of the non-important content are deleted or inserted in order to avoid the important part of the image distortion.The experimental results show that the method has a good anti-distortion performance in the ranks of non-proportional scaling.
