Personalized Saliency and its Prediction

1 code implementation9 Oct 2017 Yanyu Xu, Shenghua Gao, Junru Wu, Nianyi Li, Jingyi Yu

Specifically, we propose to decompose a personalized saliency map (referred to as PSM) into a universal saliency map (referred to as USM) predictable by existing saliency detection models and a new discrepancy map across users that characterizes personalized saliency.
