Waterloo IVC Tone Mapped Image Database

Hojatollah Yeganeh and Zhou Wang

Introduction

Tone-mapping operators (TMOs) are used to convert high dynamic range (HDR) to low dynamic range (LDR) images and provide practically useful tools for the visualization of HDR images on standard LDR displays. This dataset includes the results of different TMOs applied on various HDR contents, along with subjective quality scores given to the tone-mapped images.

We are making the IQA database available to the research community free of charge. If you use this database in your research, we kindly ask that you reference our paper listed below:

Database Specification

Twenty subjects were provided with 15 sets of tone mapped images, each of which includes 8 images generated by 8 TMOs from the same HDR image. The parameters used in all 8 TMOs are set as their default values and are not optimized. The reference HDR images are selected to represent different indoor and outdoor scenes. In the subjective test, each of the 20 observers was asked to rank the 8 images in each image set from the best to the worst. The subjective rankings for each image is then averaged, resulting in its mean ranking score within the set.
