Evaluation of HDR tone mapping methods using essential perceptual attributes
The problem of reproducing high dynamic range images on devices with restricted dynamic range has gained a lot of interest in the computer graphics community. There exist various approaches to this issue, which span several research areas including computer graphics, image processing, color vision, physiological aspects, etc. These approaches assume a thorough knowledge of both the objective an...
متن کاملPseudo Hdr Video Using Inverse Tone Mapping
In the Pseudo-Multiple-Exposure-Based Tone Fusion with Local Region Adjustment [1], it introduces a framework for inverse tone mapping which uses only one Low Dynamic Range (LDR) image to evaluate High Dynamic Range (HDR) image. First, map LDR image to HDR images using S curve. By changing the parameters of S curve, we can get different EV scenes. Then, segment the image into four different lum...
متن کاملEvaluation of Tone Mapping Operators for HDR-Video
Eleven tone-mapping operators intended for video processing are analyzed and evaluated with camera-captured and computer-generated high-dynamic-range content. After optimizing the parameters of the operators in a formal experiment, we inspect and rate the artifacts (flickering, ghosting, temporal color consistency) and color rendition problems (brightness, contrast and color saturation) they pr...
متن کاملCreating cinematic wide gamut HDR-video for the evaluation of tone mapping operators and HDR-displays
High quality video sequences are required for the evaluation of tone mapping operators and high dynamic range (HDR) displays. We provide scenic and documentary scenes with a dynamic range of up to 18 stops. The scenes are staged using professional film lighting, make-up and set design to enable the evaluation of image and material appearance. To address challenges for HDR-displays and temporal ...
متن کاملBeyond Tone Mapping: Enhanced Depiction of Tone Mapped HDR Images
High Dynamic Range (HDR) images capture the full range of luminance present in real world scenes, and unlike Low Dynamic Range (LDR) images, can simultaneously contain detailed information in the deepest of shadows and the brightest of light sources. For display or aesthetic purposes, it is often necessary to perform tone mapping, which creates LDR depictions of HDR images at the cost of contra...
