Researchers have developed an Event-guided Neural Video Codec (ENVC) that leverages event streams, which capture brightness changes between frames, to enhance the efficiency of RGB video compression. The ENVC model integrates these event streams into both motion and frame coding processes. For motion coding, it forms an event-guided motion prior and codes the residual, while for frame coding, an event-conditioned predictor refines temporal context. Evaluations on six benchmarks show significant BD-rate savings, with ENVC outperforming the DCMVC baseline by 39.13% using PSNR-RGB and 67.63% using LPIPS, demonstrating the utility of events as a complementary data source for reducing RGB coding rates.
