Personalized image observation behavior learning in fixation based personalized salient object segmentation

Abstract

Fixation as representation of one viewer’s attention are very intuitive to reflect the viewer’s observation procedure. The viewer’s observation behavior can be further revealed by analyzing fixations features. In this paper, we propose a fixation based personalized salient object segmentation method involving personal observation behavior learning. Concretely, we design three neural networks and deploy a meta-learning method. The first network is a base segmentation network that can be converted into a meta-segmentation network by meta-learning. The meta- segmentation network can learn one viewer’s observation behavior from only one sample and then generates the viewer’s segmentation network to segment the other samples. Moreover, a fusion network plays an important role in alleviating an unsuitable transmission problem and generating a final segmentation result. The experimental results demonstrate the reasonability of our observation behavior learning and the effectiveness of the three proposed neural networks.
