Inverse Tone Mapping Operator Using Sequential Deep Neural Networks Based on the Human Visual System
IEEE Access, 2018 Conventional digital displays show images with much less dynamic range than that of human visual perception. High-dynamic range (HDR) displays are being developed for viewing images with higher dynamic range than that of conventional low-dynamic range ...

Rectangularity and paramonotonicity of maximally monotone operators [PDF]
, 2012 Maximally monotone operators play a key role in modern optimization and variational analysis. Two useful subclasses are rectangular (also known as star monotone) and paramonotone operators, which were introduced by Brezis and Haraux, and by Censor, Iusem

A proximal approach to the inversion of ill-conditioned matrices [PDF]
, 2009 We propose a general proximal algorithm for the inversion of ill-conditioned matrices. This algorithm is based on a variational characterization of pseudo-inverses. We show that a particular instance of it (with constant regularization parameter) belongs

HDR-LFNet: Inverse tone mapping using fusion network
Computers & Graphics, 2023 To capture the real-world luminance values, High Dynamic Range (HDR) image processing has been developed. HDR images have a richer content than the widely-used Standard Dynamic Range (SDR) images, and are used in a number of situations, e.g. in film industry.

Low-Complexity Distortionless Techniques for Peak Power Reduction in OFDM Communication Systems
Journal of Computer Networks and Communications, 2012 A high peak-to-average power ratio (PAPR) is one of the major drawbacks to using orthogonal frequency division multiplexing (OFDM) modulation. The three most effective distortionless techniques for PAPR reduction are partial transmit sequence (PTS ...

Learning High Dynamic Range from Outdoor Panoramas
, 2017 Outdoor lighting has extremely high dynamic range. This makes the process of capturing outdoor environment maps notoriously challenging since special equipment must be used. In this work, we propose an alternative approach. We first capture lighting with
