Slowfast loss
WebbIntroduction. Video understanding is a fundamental and challenging problem in computer vision research. Temporal action detection (TAD) (Jiang et al., 2014, Heilbron et al., 2015, Liu et al., 2024b), which aims to localize the temporal interval of each action instance in an untrimmed video and recognize its action class, is particularly crucial for long-term video … Webb25 mars 2024 · A novel approach to map video embedding space to natural langugage using a two-stage approach that first extracts visual features from each frame of a video using a pre-trained CNN, and then uses the CLIP model to encode the visual features for the video domain, along with the corresponding text descriptions. The recent success of …
