Perceptual modeling for stereoscopic 3D
نویسنده
چکیده
Virtual and Augmented Reality applications typically rely on both stereoscopic presentation and involve intensive object and observer motion. A combination of high dynamic range and stereoscopic capabilities become popular for consumer displays, and is a desirable functionality of head mounted displays to come. The thesis is focused on complex interactions between all these visual cues on digital displays. The first part investigates challenges of the stereoscopic 3D and motion combination. We consider an interaction between the continuous motion presented as discrete frames. Then, we discuss a disparity processing for accurate reproduction of objects moving in the depth direction. Finally, we investigate the depth perception as a function of motion parallax and eye fixation changes by means of saccadic motion. The second part focuses on the role of high dynamic range imaging for stereoscopic displays. We go beyond the current display capabilities by considering the full perceivable luminance range and we simulate the real world experience in such adaptation conditions. In particular, we address the problems of disparity retargeting across such wide luminance ranges and reflective/refractive surface rendering. The core of our research methodology is perceptual modeling supported by our own experimental studies to overcome limitations of current display technologies and improve the viewer experience by enhancing perceived depth, reducing visual artifacts or improving viewing comfort.

Towards Reliable Stereoscopic 3D Quality Evaluation
Stereoscopic three-dimensional (3D) services have become more popular recently amid promise of providing immersive quality of experience (QoE) to the end-users with the help of binocular depth. However, various arisen artifacts in the stereoscopic 3D processing chain might cause discomfort and severely degrade the QoE. Unfortunately, although the causes and nature of artifacts have already been...

متن کاملBinocular-Combination-Oriented Perceptual Rate-Distortion Optimization for Stereoscopic Video Coding
In the chain of stereoscopic video processing, stereoscopic video coding and viewing are usually two independent stages. Conventional stereoscopic video coding puts emphasis on improving the coding efficiency by seeking the optimal trade-off between the coding bit-rate and the signal-based distortion, while neglecting the perceptual behaviors of binocular combination when stereoscopic video is ...
