A Subjective Test Framework for JPEG Pleno Quality Assessment

Abstract

The Joint Photographic Experts Group (JPEG) is currently addressing the challenges in assessing plenoptic image quality by developing new standards for both subjective and objective assessment. This process entails revisiting existing recommendations and establishing a visual quality assessment (QA) framework that considers the unique aspects of plenoptic data. The focus is currently on the light field modality, with efforts to gather expert contributions and develop tools that cater both subjective and objective QA, ensuring that the evolving requirements of plenoptic imaging QA are met. This paper presents the JPEG Pleno subjective test tool, a pivotal element in JPEG's standardization endeavor, designed to facilitate a range of subjective QA experiments that steer the decisions during a standardization process.
