Given a set of rough strokes drawn by an artist (either in pen-paper medium or in digital
medium) in raster format, the objective is to group them meaningfully and represent the group …

We present a drawing assistant for sketching and for assisting users in shading a hand drawn
sketch. The augmented reality based system uses a sketch made by a professional and …

Stroke is one of the leading causes of disability. Segmentation of ischemic stroke could help
in planning an optimal treatment. Currently, radiologists use manual segmentation, which …

We present a novel, interactive interface for the integrated cleanup, neatening, structuring
and vectorization of sketch imagery. Converting scanned raster drawings into vector …

Mandala coloring is popular among many people, from children to adults, and many studies
have revealed its benefits in mental well-being. However, our preliminary study results …

When creating freeform drawings, artists routinely employ clusters of overdrawn strokes to
convey intended, aggregate curves. The ability to algorithmically fit these intended curves to …

Line drawing vectorization is a daily task in graphic design, computer animation, and
engineering, necessary to convert raster images to a set of curves for editing and geometry …

Artist sketches often use multiple overdrawn strokes to depict a single intended curve. Humans
effortlessly mentally consolidate such sketches by detecting groups of overdrawn strokes …

Sketching is a foundational step in the design process. Decades of sketch processing
research have produced algorithms for 3D shape interpretation, beautification, animation …

A vector sketch is a popular and natural geometry representation depicting a 2D shape. When
viewed from afar, the disconnected vector strokes of a sketch and the empty space around …
