The creation of a painting in the physical world is a process that occurs over time. In the final painting, temporal history is lost, and only a static arrangement of color is all that remains. However, such information can be valuable as it may allow for editing operations that would normally be impossible to achieve using the final image. We present a new tool which decomposes a cluttered time lapse video of a painting into a sequence of translucent "stroke" layers. The layers can be edited to create new, modified instances of the original physical artwork. Since the number of reconstructed layers can be relatively large, we provide also a tool that simplifies complex spatio-temporal edits which would normally be tedious to achieve using standard image manipulation programs.
Daniel Sykora is an Associate Professor at Czech Technical University in Prague where he received PhD degree for his award winning dissertation on "Computer Assisted Analysis of Classical Cartoon Animations". After finishing PhD Daniel spent two years as a Marie Curie Fellow at Trinity College Dublin where he continued on research in cartoon animation which gave him an opportunity to work also at Walt Disney Animation Studios. Upon his return back to CTU in Prague Daniel established a small research group aim of which is to develop new algorithms which help artists to eliminate repetitive and time consuming tasks while still allowing them to use traditional animation and drawing techniques. Daniel's work received Günter Enderle Best Paper Award at Eurographics 2010 and Best Animation Paper at NPAR 2011. Besides academic career Daniel and his group tightly cooperates with renowned industrial partners including Adobe or TVPaint Development in order to turn research ideas into practical products.
Czech Technical University in Prague is a prestigious university recognized both in the Czech Republic and abroad. It has more than three-hundred-year history. The Department of Computer Graphics and Interaction (DCGI) is a part of the Faculty of Electrical Engineering. It was founded in 2008 by members of former Computer Graphics Group at the Department of Computer Science and Engineering. The research activities of DCGI focus on two main directions: Computer Graphics and Human-Computer Interaction.
