AIGCOIQA2024: Perceptual Quality Assessment of AI Generated Omnidirectional Images

TL;DR

This paper introduces AIGCOIQA2024, a large-scale database and benchmark for assessing the perceptual quality of AI-generated omnidirectional images, addressing a gap in specialized IQA criteria for such images.

Contribution

It establishes a new database with subjective quality assessments and evaluates existing IQA models, providing a foundation for future research in AI-generated omnidirectional image quality.

Findings

Created a database of 300 AI-generated omnidirectional images.

Conducted subjective assessments from multiple perspectives.

Evaluated state-of-the-art IQA models on the new database.

Abstract

In recent years, the rapid advancement of Artificial Intelligence Generated Content (AIGC) has attracted widespread attention. Among the AIGC, AI generated omnidirectional images hold significant potential for Virtual Reality (VR) and Augmented Reality (AR) applications, hence omnidirectional AIGC techniques have also been widely studied. AI-generated omnidirectional images exhibit unique distortions compared to natural omnidirectional images, however, there is no dedicated Image Quality Assessment (IQA) criteria for assessing them. This study addresses this gap by establishing a large-scale AI generated omnidirectional image IQA database named AIGCOIQA2024 and constructing a comprehensive benchmark. We first generate 300 omnidirectional images based on 5 AIGC models utilizing 25 text prompts. A subjective IQA experiment is conducted subsequently to assess human visual preferences from three perspectives including quality, comfortability, and correspondence. Finally, we conduct a benchmark experiment to evaluate the performance of state-of-the-art IQA models on our database. The database will be released to facilitate future research.
