In a traditional streaming system, the field of view (FOV) of an image is limited based on the FOV of the camera. One solution is the use of a pan/tilt camera, yet this is difficu...

We present an intuitive scheme for lossy color-image compression: Use the color information from a few representative pixels to learn a model which predicts color on the rest of t...

This paper presents an objective metric for the perceived quality of low bit rate compressed video. Frames are decomposed into several frequency bands at multiple scales and a mot...
