Assessment of HDR-formats: Challenges of Perceptual Evaluation and Objective Measurements of Camera Captured Contents
Benoit Pochon · London Imaging Meeting · 2024
Recent cameras, especially smartphones, provide HDR formats for capturing videos and photos. For end-users, these formats hold great potential to enhance the visualization experience of captured content on supported displays. Consequently, there is a need to rigorously and objectively evaluate the content produced in HDR-Formats. In this article, we will address the current challenges in perceptual evaluation and objective measurement of camera footage in HDR formats, taking a practical perspective. Based on the results of a perceptual experiment conducted with HDR video formats, we will underline the importance of viewing conditions and signals levels, and list open questions about evaluating HDR still images. In a second part, we will provide an overview of objective measurements for HDR formats with the use of ICtCp.
