Modeling the impact of spatial resolutions on perceptual quality of immersive image/video

摘要

We have attempted to investigate the impact of spatial resolutions on perceptual quality of immersive video/image contents rendered using a head mounted display. Subjective quality assessment is performed using the popular HTC Vive system. As demonstrated through the extensive experiments, spatial resolution impact on immersive image perceptual quality can be well described by an exponential model with a single model parameter, with averaged root mean squared errors (RMSE) less than 5% and Pearson correlation (PC) coefficient larger than 0.94. Model parameter characterizes the quality degradation speed when decreasing the spatial resolution, and now is derived using the least-squared-error fitting optimization.
