The left figures show results of our HiCoM on N3DV [1] and Meet Room [2] datasets, where "Res" indicates video resolution. The right figure is tested on the N3DV [1] dataset, where the radius of the circle corresponds to the average storage per frame and the method in the top left corner demonstrates the best performance.
