Abstract: Highlights•A novel sketch recognition framework named Sketch-SparseNet is proposed.•SD3B to directly establish spatial relationships of disconnected stroke points.•SmoothAlign Loss to minimize the gap between features from our SD3B and CNNs.•Achieve SOTA performance on both the QuickDraw414k and TU-Berlin datasets.
