Abstraction is at the heart of sketching due to the simple and minimal nature of line
drawings. Abstraction entails identifying the essential visual properties of an object or scene …

We present the Sketchy database, the first large-scale collection of sketch-photo pairs. We
ask crowd workers to sketch particular photographic objects sampled from 125 categories …

This paper aims to conduct a comprehensive study on facial-sketch synthesis (FSS).
However, due to the high cost of obtaining hand-drawn sketch datasets, there is a lack of a …

In this paper, we present a method for converting a given scene image into a sketch using
different types and multiple levels of abstraction. We distinguish between two types of …

In this paper we propose a novel abstraction-aware sketch-based image retrieval framework
capable of handling sketch abstraction at varied levels. Prior works had mainly focused on …

Significant progress has been made with image stylization using deep learning, especially
with generative adversarial networks (GANs). However, existing methods fail to produce …

Fine-grained sketch-based image retrieval (FG-SBIR) addresses the problem of retrieving a
particular photo instance given a user's query sketch. Its widespread applicability is however …

Synthesizing face sketches from real photos and its inverse have many applications.
However, photo/sketch synthesis remains a challenging problem due to the fact that photo …

Sketching is a powerful tool for creating abstract images that are sparse but meaningful.
Sketch understanding poses fundamental challenges for general-purpose vision algorithms …

A sketch is one of the most intuitive and versatile tools humans use to convey their ideas
visually. An animated sketch opens another dimension to the expression of ideas and is …
