Research > Gaze-Contingent Compression

Goal: Extreme compression for multimedia content.

Implementation: Eye-gaze position indicates the area of the image that requires high-quality coding. Peripheral part of the image is encoded with lower quality. Peripheral image degradation is performed according to a visual sensitivity function that accounts for distribution of the light sensing cells in the human eye. Such approach allows compressing a visual source by up to 3 times without a viewer noticing compression artifacts.

Project Status: Looking for students interested in the project. The students will participate in applying gaze contingent compression methods to the 3D enviroments.
