Abstract
Since consumer devices have clef resolution sizes of display panels, digital images arc, frequently required to be resized for each display adaptation. In this paper, we define DCT-based distortion measures to quantitatively evaluate both scaling distortion and shape distortion generated by downsizing. By utilizing the distortion measures, we propose a novel content-aware image retargeting algorithm. The proposed algorithm can not only satisfy demands of users without the loss of semantic information in images but also is computationally efficient since the digital images are typically stored in DCT-based compression formal. Experimental results show that the proposed method can achieve higher subjective quality with significantly reduced computational loads as compared with existing methods(1).
