DiffusionVMR: Diffusion Model for Joint Video Moment Retrieval and Highlight Detection.

Video moment retrieval and highlight detection have received attention in the current era of video content proliferation, aiming to localize moments and estimate clip relevances based on user-specific queries. Most existing methods approach these challenges from a discriminative learning perspective, focusing on learning the correspondence between query and activity boundary locations through complex cross-modal interactions. However, the continuous nature of video content often results in unclear boundaries between temporal events.
