DifferSketching: How Differently Do People Sketch 3D Objects?

Abstract

the existing datasets. We analyze the collected data at three levels, i.e., sketchlevel, stroke-level, and pixel-level, under both spatial and temporal characteristics, and within and across groups of creators. We found that the drawings by professionals and novices show significant differences at stroke-level, both intrinsically and extrinsically. We demonstrate the usefulness of our dataset in two applications: (i) freehand-style sketch synthesis, and (ii) posing it as a potential benchmark for sketch-based 3D reconstruction. Our dataset and code are available at https://chufengxiao.github.io/DifferSketching/.CCS Concepts: • Applied computing → Arts and humanities; • Humancentered computing → Interaction design; User studies; • Computing methodologies → Graphics systems and interfaces.
