Patent number: 11823432Abstract: The present disclosure provides a saliency prediction method and system for a 360-degree image based on a graph convolutional neural network. The method includes: firstly, constructing a spherical graph signal of an image of an equidistant rectangular projection format by using a geodesic icosahedron composition method; then inputting the spherical graph signal into the proposed graph convolutional neural network for feature extraction and generation of a spherical saliency graph signal; and then reconstructing the spherical saliency graph signal into a saliency map of an equidistant rectangular projection format by using a proposed spherical crown based interpolation algorithm. The present disclosure further proposes a KL divergence loss function with sparse consistency. The method can achieve excellent saliency prediction performance subjectively and objectively, and is superior to an existing method in computational complexity.Type: GrantFiled: February 5, 2023Date of Patent: November 21, 2023Assignee: SHANGHAI JIAO TONG UNIVERSITYInventors: Chenglin Li, Haoran Lv, Qin Yang, Junni Zou, Wenrui Dai, Hongkai Xiong
