Fast High Quality Image and Video Background Removal with CUDA
Abstract:

A tool to efficiently and easily cut out objects from a taken picture has great practical value. In this session we present aspects on how to efficiently implement such a tool with CUDA and the NPP library based on the GrabCut approach by Rother et al. Through GPU acceleration both runtime and accuracy is improved compared to CPU based implementations such as the one in MS Word 2011. Further we show how to extend our GPU implementation to enable live background removal in a webcam video stream.
