LIVE Tone-Mapped High Dynamic Range Video Quality Assessment Database

Introduction

High Dynamic Range (HDR) videos are able to represent wider ranges of contrasts and colors than Standard Dynamic Range (SDR) videos, giving more vivid experiences. Due to this, HDR videos are expected to grow into the dominant video modality of the future. However, HDR videos are incompatible with existing SDR displays, which form the majority of affordable consumer displays on the market. Because of this, HDR videos must be processed by tone-mapping them to reduced bit-depths to service a broad swath of SDR-limited video consumers. Here, we analyze the impact of tone-mapping operators on the visual quality of streaming HDR videos. To this end, we built the first large-scale subjectively annotated open-source database of compressed tone-mapped HDR videos, containing 15,000 tone-mapped sequences derived from 40 unique HDR source contents. The videos in the database were labeled with more than 750,000 subjective quality annotations, collected from more than 1,600 unique human observers. We demonstrate the usefulness of the new subjective database by benchmarking objective models of visual quality on it. We envision that the new LIVE Tone-Mapped HDR (LIVE-TMHDR) database will enable significant progress on HDR video tone mapping and quality assessment in the future.

Database Description

The LIVE Tone-Mapped HDR Database contains 15,000 video sequences generated from 40 high-quality (pristine) source High Dynamic Range videos by applying 10 open-source tone-mapping operators (TMOs), two proprietary TMOs, and by applying manual tone-mapping by a human expert colorist. Each open-source TMO was deployed at four spatial parameter settings and three temporal modes, thereby eliciting authentic spatio-temporal distortions that arise during tone-mapping. We obtained high-quality subjective ratings for all test videos by collecting over 750,000 subjective opinions from over 1,600 unique human observers.
