Empirical Evaluation of Real-Time Video Foveation

The foveated video compression techniques were developed to deliver high-quality video at lower bitrates, matching the nonuniform sampling in human's visual system (HVS). In these techniques the fovea region i.e., the area of about 2-5 degree around gaze centre is compressed at the highest bitrate. Allocating lower bitrates to other regions based on their distances from fovea decreases the overall bitrate. This technology could be used in streaming high quality videos over the Internet with minimal bandwidth consumption. In this study we evaluate our implementation of real-time foveation algorithm as the first step for foveated video streaming.
