Abstract: This paper presented an image resizing method which can preserve the content and the shape of salient objects.Image can be resized by using traditional seam carving and warping techniques.First,the proposed method produces the significant map of clear shape and structure by combining the saliency detection via graph-based manifold ranking and gradient energy information.And then appropriate resizing methods are determined according to the size of the resizing scale by using the former significant map.Finally,image can be resized by the classic seam carving method or the resizing method of deformation based on energy optimization according to the comparison results.A lot of comparison results show that the method can keep both important content and shape and structure of salient objects.
