Opening Session
General Chair : Jean-Christophe Burie

Keynote Talk
Chair : Pau Riba

Professor Timothy Hospedales
University of Edinburgh
Title : All about Free-hand sketch
Abstract : In this talk I will give a tour through the world of free-hand sketch from the perspective of SketchX lab. We will look at diverse sketch representations and diverse applications spanning recognition, retrieval, abstraction, synthesis and competitive sketching. In the process we will see a diverse set of machine learning tools, both classic and cutting edge, that can help to improve accuracy, efficiency, fidelity, and robustness of sketch-related tasks.
