Temporally coherent luminance-to-luma mapping for high dynamic range video coding with H.264/AVC
This paper presents a technique for the efficient compression of high dynamic range video (HDR) sequences. Such video sequences usually represent several orders of magnitude of r...

Acquisition and Encoding of High Dynamic Range Images using Inverse Tone Mapping
A two layer coding algorithm for high dynamic range images is discussed. In the first layer, a low dynamic range image is encoded by a conventional codec, and then the residual in...

Subband encoding of high dynamic range imagery
The transition from traditional 24-bit RGB to high dynamic range (HDR) images is hindered by excessively large file formats with no backwards compatibility. In this paper, we prop...

High Dynamic Range image tone mapping based on local Histogram Equalization
High Dynamic Range (HDR) images can represent the acquired scene with a greater dynamic range of luminance than classical Low Dynamic Range (LDR) ones. Despite the recent diffusio...
