A Sketch-based Interface for Photo Pop-up

Jonathan Ventura, Stephen DiVerdi (Adobe) and Tobias Hollerer

We present sketch-based tools for single-view modeling which allow for quick 3D mark-up of a photograph. With our interface, detailed 3D models can be produced quickly and easily. After establishing the background geometry, foreground objects can be cut out using our novel sketch-based segmentation tools. These tools make use of the stroke speed and length to help determine the user’s intentions. Depth detail is added to the scene by drawing occlusion edges. Such edges play an important part in human scene understanding, and thus provide an intuitive form of input to the modeling system. Initial results and evaluation show that our methods produce good 3D results in a short amount of time and with little user effort, demonstrating the usefulness of an intelligent sketching interface for this application domain.
