From: An event-oriented diffusion-refinement method for sparse events completion

The event completion results on N-MNIST dataset from input with 256 events (a) and 128 events (b). STCL leads to too dense events which may lose local shape, e.g. ‘7’ in (b), while results of PoinTr and VRCNet tend to suffer from missing entries. Our method maintains both overall event completeness and local shape. Green and red indicate positive and negative events respectively.
