The Sketchy Database: Learning to Retrieve Badly Drawn Bunnies

The Sketchy Database is the first large-scale collection of sketch-photo pairs. Crowd workers sketch 12,500 objects from 125 categories and generate 74,425 sketches. The system trains cross-domain CNNs to embed sketches and photographs, which leads to state-of-the-art sketch-based image retrieval.

Fidelity vs. Simplicity: a Global Approach to Line-Drawing Vectorization

The first line drawing vectorization algorithm that explicitly balances fidelity to the input bitmap with simplicity of the output curves. The global optimization generates few yet accurate curves and disambiguates curve topology at junctions by favoring the simplest interpretations overall.

Learning to Simplify: Fully Convolutional Networks for Rough Sketch Cleanup

A novel technique for fully automatic simplification of sketch drawings. By learning a series of convolution operators from a dataset of rough and simplified-sketch drawing pairs, this method overcomes the limitation of existing methods that require vector inputs. It outperforms existing approaches in a user study.

My Text in Your Handwriting

This texture-synthesis method for generating believable handwriting replicates the style of a specific author. In user studies, it is capable of fooling casual observers, and it works on historical figures.
