Tiivistelmä
This paper presents a demonstrator setup for real-time HEVC encoding with gaze-based region of interest (ROI) detection. This proof-of-concept system is built on Kvazaar open-source HEVC encoder and Pupil eye tracking glasses. The gaze data is used to extract the ROI from live video and the ROI is encoded with higher quality than non-ROI regions. This demonstration illustrates that performing HEVC encoding with non-uniform quality reduces bit rate by 40-90% and complexity by 10-35% over that of the conventional approaches with negligible to minor deterioration in subjective quality.
