Reduced Frame Quantization in Video Coding
We vary the quantization parameter in H.264 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. As the motion compensation ...

Efficient Coding of Motion Vector Predictor Using Phased-in Code
The H.264/AVC video coding standard performs inter prediction using variable block sizes to improve coding efficiency. Since we predict not only the motion of the homogeneous regio...

Feature-Oriented Rate Shaping of Pre-Compressed Image/Video
Rate shaping plays an important role in transmitting compressed video on a network with dynamic bandwidth. In this paper, we present a scheme for rate shaping JPEG/MPEG-precompres...

Optimizing Algorithms for Region-of-Interest Video Compression, with Application to Mobile Telehealth
Wireless communication of video poses constraints on information capacity. Region-of-Interest (ROI) video coding provides higher quality in the ROI, but poorer quality in the back...
