iTM-Net: Deep Inverse Tone Mapping Using Novel Loss Function Considering Tone Mapping Operator

Inverse Tone Mapping by

The introduction of High Dynamic Range Imaging in computer graphics has produced a novelty in Imaging that can be compared to the introduction of colour photography or even more. Light can now be captured, stored, processed, and finally visualised without losing information. Moreover, new applications that can exploit physical values of the light have been introduced such as re-lighting of synt...

Pseudo 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...

Development of a Perceptual Tone Mapping Operator

Modeling a Generic Tone-mapping Operator

Although several new tone-mapping operators are proposed each year, there is no reliable method to validate their performance or to tell how different they are from one another. In order to analyze and understand the behavior of tone-mapping operators, we model their mechanisms by fitting a generic operator to an HDR image and its tone-mapped LDR rendering. We demonstrate that the majority of b...

Robust Parameter Estimation for Tone Mapping Operator

Tone Mapping Operators are used to compress a large range of pixel luminances into a smaller range that is suitable for display on devices with limited dynamic range. This work presents effective and easy to use Tone Mapping Operator based on last ideas in this direction. The estimation process uses sampling method. Essential attention was devoted to providing robustness of algorithm parameter ...
