Abstract: Recently, interest about images and photos in omni-directional format (360°, field-of-view) are gradually increasing. To ensure high image quality at the transfer, storing and sharing of such images, advanced compression tools are required. This paper provides an objective-based comparison of emerging compression algorithms (JPEG XL, HEIC, AVIF), implemented in a graphic viewer and editor, for 360° images. For this purpose, four images from publicly available databases and two self-made images are used and compressed to different quality levels. Different objective metrics are used to evaluate the visual quality of images. Compared to the popular image-based compression algorithm JPEG, the emerging compression tools show high efficiency and applicability for omnidirectional images.

Overview of the High Efficiency Video Coding (HEVC) Standard
TL;DR: The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards-in the range of 50% bit-rate reduction for equal perceptual video quality.
FSIM: A Feature Similarity Index for Image Quality Assessment
TL;DR: A novel feature similarity (FSIM) index for full reference IQA is proposed based on the fact that human visual system (HVS) understands an image mainly according to its low-level features.

TL;DR: A simple mathematical relationship is derived between the peak-signal-to-noise ratio and the structural similarity index measure which works for various kinds of image degradations such as Gaussian blur, additive Gaussian white noise, jpeg and jpeg2000 compression.

Image information and visual quality
Hamid R. Sheikh,Alan C. Bovik +1 more
TL;DR: An image information measure is proposed that quantifies the information that is present in the reference image and how much of this reference information can be extracted from the distorted image and combined these two quantities form a visual information fidelity measure for image QA.

Gradient Magnitude Similarity Deviation: A Highly Efficient Perceptual Image Quality Index
TL;DR: It is found that the pixel-wise gradient magnitude similarity (GMS) between the reference and distorted images combined with a novel pooling strategy-the standard deviation of the GMS map-can predict accurately perceptual image quality.
