This paper introduces a public (OMNIQAD) database of omnidirectional (360 degrees) images distorted by various ways and techniques, which can serve as a basic source for various research in the field of objective and subjective quality assessment of an immersive multimedia content. Compression-based distortions were applied using traditional JPEG and several emerging image compression standards, for instance, HEIC, AVIF and JPEG XL. Other types of distortion included Gaussian and impulse noise. The database offers eleven reference omnidirectional images of different character (374 distorted images in total). For the evaluation of distorted and compression-based corrupted images, several objective quality metrics were adopted. Link to a repository containing the resulting objective scores and the database of images are included in this paper.

Spatial hearing is a complex phenomenon that allows humans to use ear signals and their experience to locate sound sources. In the conducted experiment, the emphasis was on sound sources localisation accuracy in VAS for various HRTFs, specifically generic HRTF from the Club Fritz database and personalised HRTF measured for each listener at a designated workplace at the Department of Radioelectronics.
