Tetris: Tile-level Sampling for Efficient and High-Fidelity Video Object Tracking 事件

Tetris: Tile-level Sampling for Efficient and High-Fidelity Video Object Tracking arXiv:2605.25538v1 Announce Type: new Abstract: Track materialization converts raw video into reusable object tracks that downstream queries can run against without rerunning tracking, but extracting those tracks efficiently and with high fidelity remains expensive. Prior systems reduce cost through temporal frame sampling, erasing the inter-frame motion that fine-grained tracking requires. In stationary video, ho
