ABSTRACT
As mobile video traffic is becoming dominant, balancing the mobile video quality and bandwidth usage is a relevant but hard problem. Particularly, in this project, we attempt to reduce the bandwidth usage of video chats through frame rate adaption. The key idea of this project is to save bandwidth through reducing frame rate at the sender and interpolate the `missing' frames at the receiver for a video chat. Additionally, the sender dynamically adapts the frame rate with respect to inertial sensor readings in order to keep the scene change between consecutive frames small and prevent strong artifacts from the frame interpolation.

LBVC: towards low-bandwidth video chat on smartphones
MMSys '15: Proceedings of the 6th ACM Multimedia Systems ConferenceVideo chat apps enable users to stay in touch with their family, friends and colleagues. However, they consume a lot of bandwidth and hence can quickly use up a monthly data plan quota, which is a high-cost resource on smartphones. In this paper, we ...
Fast frame-rate up-conversion of depth video via video coding
MM '11: Proceedings of the 19th ACM international conference on MultimediaRecent development of depth sensors has facilitated the progress of 2D-plus-depth methods for 3D video representation, for which frame-rate up-conversion (FRUC) of depth video is a critical step. However, due to the computational cost of state-of-the-...
Video frame interpolation via optical flow estimation with image inpainting
AbstractAs we all know, video frame rate determines the quality of the video. The higher the frame rate, the smoother the movements in the picture, the clearer the information expressed, and the better the viewing experience for people. Video ...
