Abstract
A method and a system for rendering video images in virtual reality (VR) scenes are provided. The method includes providing a video image at a current time point, dividing the video image at the current time point into a plurality of sub-regions, inputting image feature information of the sub-regions and acquired user viewpoint feature information into a trained attention model for processing to obtain attention coefficients of the sub-regions indicating probability values at which user viewpoints at a next time point fall into the sub-regions, rendering the sub-regions based on the attention coefficients of the sub-regions to obtain a rendered video image at the current time point, inputting the attention coefficients of the sub-regions and the image feature information of the sub-regions into a trained user eyes trajectory prediction model for processing, obtaining user eyes trajectory information in a current time period, dividing, for video images at subsequent time points within the current time period, the video images at the subsequent time points into a plurality of sub-regions, calculating attention coefficients of the sub-regions in a video image at each of the subsequent…
