Quicktoon: a real-time video stylization and sharing system on general processors

We present a video stylization and sharing system named QuickToon, which supports generating a variety of useful and pleasing visual effects and allows easy use in video chat or sharing via social networking services (SNS). Based on our highly efficient edge-preserving smoothing filter, non-photo-realistic video rendering effects can be generated on the fly such as skin beautification, cartoon-like rendition, object outline, pencil sketch, and color stroke. Without requiring any GPUs that would otherwise seriously limits portability, the QuickToon system runs comfortably in real time for VGA- or HD-sized videos on general processors such as CPUs. The system can take in video frames either from a live webcam feed or any photos/videos from the local store, while the transformed imagery can be used in a live Skype video call, or saved locally, or uploaded and shared to SNS with one click. We demonstrate with concrete examples the functionality of this system, and underline its utility in video communication and photo/video sharing.
