Dynamic visual saliency in image sequences

Abstract : Our thesis research is concerned with the estimation of motion saliency in image sequences. First, we have defined an original method to detect frames in which a salient motion is present. For this, we propose a framework relying on a deep neural network, and on the compensation of the dominant camera motion. Second, we have designed a method for estimating motion saliency maps. This method requires no learning. The motion saliency cue is obtained by an optical flow inpainting step, followed by a comparison with the initial flow. Third, we consider the problem of trajectory saliency estimation to handle progressive saliency over time. We have built a weakly supervised framework based on a recurrent auto-encoder that represents trajectories with latent codes. Performance of the three methods was experimentally assessed on real video datasets.
