Secure High Dynamic Range Images [PDF]
International Journal of Advanced Computer Science and Applications, 2016 En este documento, se propone un algoritmo de mapeo de tonos para producir imágenes LDR (rango dinámico limitado) a partir de imágenes HDR (alto rango dinámico). En el enfoque, se aplican funciones no lineales para comprimir el rango dinámico de las imágenes HDR. Las herramientas de seguridad se aplicarán a las imágenes LDR resultantes y su efectividad

High dynamic range imaging with a single-mode pupil remapping system : a self-calibration algorithm for redundant interferometric arrays [PDF]
, 2006 The correction of the influence of phase corrugation in the pupil plane is a fundamental issue in achieving high dynamic range imaging. In this paper, we investigate an instrumental setup which consists in applying interferometric techniques on a single ...

High Dynamic Range and Super-Resolution Imaging From a Single Image
IEEE Access, 2018 This paper presents an algorithm for high dynamic range (HDR) and super-resolution (SR) imaging from a single image. First, we propose a new single image HDR imaging (HDRI) method based on the Retinex approach and exploit a recent single image SR method ...

Single-particle-sensitive imaging of freely propagating ultracold atoms [PDF]
, 2009 We present a novel imaging system for ultracold quantum gases in expansion. After release from a confining potential, atoms fall through a sheet of resonant excitation laser light and the emitted fluorescence photons are imaged onto an amplified CCD ...

RADIANCE DOMAIN COMPOSITING FOR HIGH DYNAMIC RANGE IMAGING [PDF]
ICTACT Journal on Image and Video Processing, 2013 High dynamic range imaging aims at creating an image with a range of intensity variations larger than the range supported by a camera sensor. Most commonly used methods combine multiple exposure low dynamic range (LDR) images, to obtain the high dynamic ...

De-ghosting in High Dynamic Range Imaging Based on Intensity Scaling Cue
Advances in Electrical and Computer Engineering, 2020 A High Dynamic Range (HDR) image produced from a sequence of low dynamic range (LDR) images can contain motion artefacts (ghosting) if the scene contains moving objects.

Rendering high dynamic range images [PDF]
SPIE Proceedings, 2000 In this paper, we review several algorithms that have been proposed to transform a high dynamic range image into a reduced dynamic range image that matches the general appearance of the original. We organize these algorithms into two categories: tone reproduction curves (TRCs) and tone reproduction operators (TROs).

Speckle noise and dynamic range in coronagraphic images [PDF]
, 2007 This paper is concerned with the theoretical properties of high contrast coronagraphic images in the context of exoplanet searches. We derive and analyze the statistical properties of the residual starlight in coronagraphic images, and describe the ...

On-sky observations with an achromatic hybrid phase knife coronagraph in the visible [PDF]
, 2006 CONTEXT: The four-quadrant phase mask stellar coronagraph, introduced by D. Rouan et al., is capable of achieving very high dynamical range imaging and was studied in the context of the direct detection of extra-solar planets.
