Seam carving, an image re-targeting method, works by progressively finding and removing connected paths of low energy pixels in an image until a desired image aspect ratio is reached. In this paper, we first cast the problem of minimizing an energy function as that of minimizing a distortion cost. We then leverage on our understanding of image quality metrics/ distortion metrics in proposing a perceptually relevant energy function. Experimental results show that our proposed energy function can generate more desirable resized images in which the original structures of the images are better preserved.
