AllTracker: Efficient Dense Point Tracking at High Resolution

AllTracker estimates long-range point tracks by computing the flow field between a query frame and every other frame in a video. Unlike existing methods, it produces high-resolution, dense (all-pixel) correspondence fields, enabling tracking at 768x1024 resolution on a 40G GPU. Instead of frame-by-frame processing, AllTracker processes a window of flow problems simultaneously, significantly improving long-range flow estimation. This efficient model (16 million parameters) achieves state-of-the-art accuracy, benefiting from training on a diverse set of datasets.
