Content-aware media retargeting based on deep importance map

Abstract: We present a neural network to estimate the visual information of important pixels in image and video, which is used in content-aware media retargeting applications. Existing techniques are successful in proposing retargeting methods. Yet, the serious distortion and the shrunk problem in the retargeted results still need to be investigated due to the limitations in the methods used to analyze visual attention. To accomplish this, we propose a network to define the importance map, which is sufficient to describe the energy of the significant regions in image/video. With this strategy, more ideal results are obtained from our system. Besides, the objective evaluation presented in this paper shows that our media retargeting system can achieve better and more plausible results than those of other works. In addition, our proposed importance map performs well in the enlarge operator and on the "difficult-to-resize" images.
