Method for evaluating tone mapping operators for natural high dynamic range images
نویسندگان
چکیده
High dynamic range (HDR) imaging seems to have developed to a level of soon being a standard feature in consumer cameras. This study was motivated by the need for evaluating tone mapping operators especially for consumer imaging applications. A no-reference method based on ISO 20462-2:2005 triplet comparison was created for evaluating tone mapping operators. Multiple HDR test images were photographed and the method was validated by evaluating 25 tone mapping operators with five test images. Tone mapping operators were evaluated based on image naturalness and pleasantness. The results indicate that the method successfully ranked the method in terms of naturalness and pleasantness. The test image set could be improved for example based on an imaging photo space for HDR photography. The test images of this study are available for non-commercial research purposes.

Tone-mapping operators (TMOs) that convert high dynamic range (HDR) to low dynamic range (LDR) images pro-vide practically useful tools for the visualization of HDR images on standard LDR displays. Different TMOs create different tonemapped images, and a natural question is which one has the best quality. Without an appropriate quality measure, different TMOs cannot be compared, and further imp...

متن کاملSMQT-based Tone Mapping Operators for High Dynamic Range Images
In this paper, tone mapping operations based on the nonlinear Successive Mean Quantization Transform (SMQT) are proposed in order to convert high dynamic range images to low dynamic range images. A SMQTbased tone mapping applied on the luminance channel is derived as well as a SMQT-based method working directly on all RGB channels. Both methods are compared to other state-of-the-art methods and...
متن کاملPerceptual evaluation of tone mapping operators with real-world scenes
A number of successful tone mapping operators for contrast compression have been proposed due to the need to visualize high dynamic range (HDR) images on low dynamic range devices. They were inspired by fields as diverse as image processing, photographic practice, and modeling of the human visual systems (HVS). The variety of approaches calls for a systematic perceptual evaluation of their perf...
