Abstract
We develop a model that expresses the joint impact of spatial resolution s and JPEG compression quality factor qf on immersive image quality. The model is expressed as the product of optimized exponential functions of these factors. The model is tested on a subjective database of immersive image contents rendered on a head mounted display (HMD). High Pearson correlation and Spearman correlation (> 0.95) and small relative root mean squared error (< 5.6%) are achieved between the model predictions and the subjective quality judgements. The immersive ground-truth images along with the rest of the database are made available for future research and comparisons.
