Modeling the Perceptual Quality of Immersive Images Rendered on Head Mounted Displays: Resolution and Compression

摘要

We develop a model that expresses the joint impact of spatial resolutionn$s$nand JPEG compression quality factorn$q^{f}$non 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. 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.
