SKETCHES are created by humans through an iterative process and reflect one’s sketching skills, taste, world perception and even character IN JUST A SET OF SPARSE LINES. Being the result of semantic, perceptual, or conceptual processing, sketches are distinctive from photos.

While the Computer Vision and Machine Learning communities have firmly invested in reasoning with photos, sketch data just recently got into the spotlight. This shift of focus on using sketch data has already started to cause profound impact on many facets of research on computer vision, computer graphics, machine learning, HCI and artificial intelligence at large. Sketch has not only been used for image RETRIEVAL, 3D MODELING, USER INTERFACE DESIGN, but also as a key enabler in our fundamental understanding of VISUAL ABSTRACTION, CREATIVITY, and EXPRESSIVITY. Developing such understanding is impossible with photos.

This (series of) workshop aims to BRING TOGETHER RESEARCHERS FROM INTERDISCIPLINARY RESEARCH FIELDS in the community to consolidate cross-discipline insights, IDENTIFY AND ENCOURAGE NEW RESEARCH DIRECTIONS, and ultimately foster the growth of the sketch research community.

The topics of primary interest for this workshop are those that study and exploit an expressive power of sketches. We encourage interdisciplinary research lying at the intersection of CV (computer vision), ML (machine learning) and CG (computer graphics), HCI (human-computer interaction), or UX (user experience). Specifically, topics include but are not limited to:

Sketch understanding and representation:
   - sketch and human perception
   - sketch social and cultural impact
   - synthetic 2D/3D sketch synthesis
   - sketch abstraction
   - synthetic sketch quality assessment
   - sketch recognition
   - sketch segmentation/grouping
   - sketch captioning
   - sketch representation

Sketch and human creativity:
   - sketch for human creativity
   - sketch-based ideation and product prototyping
   - sketch-based modeling
   - sketch-based editing
   - sketching interfaces
   - sketching in AR/VR, gesture recognition for sketching
   - style transfer in scene sketching, portraits or animation

Multi-modal sketch applications:
   - 2D sketch-based image retrieval (SBIR)
   - 2D/3D sketch-based 3D shape retrieval
   - novel sketch-based datasets and its applications


The submitted papers must be an unpublished work on the topics summarized above. Papers will undergo full double-blind peer review by 3-5 program committee members. There is neither a rebuttal nor a second review cycle. The papers will be published in conjunction with ICCV 2021 proceedings. The Best Paper will be selected by a program committee.
