Sketches are highly expressive, inherently capturing subjective and fine-grained visual
cues. The exploration of such innate properties of human sketches has, however, been …

Free-hand sketches are highly illustrative, and have been widely used by humans to depict
objects or stories from ancient times to the present. The recent prevalence of touchscreen …

What makes free-hand sketches appealing for humans lies with its capability as a universal
tool to depict the visual world. Such flexibility at human ease, however, introduces abstract …

We contribute the rst large-scale dataset of scene sketches, SketchyScene, with the goal of
advancing research on sketch understanding at both the object and scene level. The dataset …

In this work we aim to develop a universal sketch grouper. That is, a grouper that can be
applied to sketches of any category in any domain to group constituent strokes/segments …

In this paper, we aim to explore the fine-grained perception ability of deep models for the
newly proposed scene sketch semantic segmentation task. Scene sketches are abstract …

This paper addresses cross-domain visual search, where visual queries retrieve category
samples from a different domain. For example, we may want to sketch an airplane and …

Modelling human free-hand sketches has become topical recently, driven by practical
applications such as fine-grained sketch based image retrieval (FG-SBIR). Sketches are …

Given pixel-level annotated data, traditional photo segmentation techniques have achieved
promising results. However, these photo segmentation models can only identify objects in …

With the development of digital devices and pressure sensing equipment, research into
freehand sketches from touch-screen interfaces has increased significantly in recent years …
