Resolution Enhancement in Coherent Diffraction Imaging Using High Dynamic Range Image
Photonics, 2021 In a coherent diffraction imaging (CDI) system, the information of the sample is retrieved from the diffraction patterns recorded by the image sensor via multiple iterations.

Supervised Image Segmentation for High Dynamic Range Imaging
2023 IEEE International Conference on Acoustics, Speech, and Signal Processing Workshops (ICASSPW), 2023 Regular cameras and cell phones are able to capture limited luminosity. Thus, in terms of quality, most of the produced images from such devices are not similar to the real world. They are overly dark or too bright, and the details are not perfectly visible. Various methods, which fall under the name of High Dynamic Range (HDR) Imaging, can be utilised

Characterization for High Dynamic Range Imaging [PDF]
Computer Graphics Forum, 2008 AbstractIn this paper we present a new practical camera characterization technique to improve color accuracy in high dynamic range (HDR) imaging. Camera characterization refers to the process of mapping device‐dependent signals, such as digital camera RAW images, into a well‐defined color space.

Exploiting Light Polarization for Deep HDR Imaging from a Single Exposure
Sensors, 2023 In computational photography, high dynamic range (HDR) imaging refers to the family of techniques used to recover a wider range of intensity values compared to the limited range provided by standard sensors.

Visualization of high dynamic range images [PDF]
Proceedings. International Conference on Image Processing, 2003 A novel paradigm for information visualization in high dynamic range images is presented in this paper. These images, real or synthetic, have luminance with typical ranges many orders of magnitude higher than that of standard output/viewing devices, thereby requiring some processing for their visualization.

High-Dynamic-Range CT Reconstruction Based on Varying Tube-Voltage Imaging. [PDF]
PLoS ONE, 2015 For complicated structural components characterized by wide X-ray attenuation ranges, the conventional computed tomography (CT) imaging using a single tube-voltage at each rotation angle cannot obtain all structural information.

High Dynamic Range Imaging with TDC-Based CMOS SPAD Arrays
Instruments, 2019 This paper investigates the use of image sensors based on complementary metal−oxide−semiconductor (CMOS) single-photon avalanche diodes (SPADs) in high dynamic range (HDR) imaging by combining photon counts and timestamps. The proposed method

Sparse signal recovery from modulo observations
EURASIP Journal on Advances in Signal Processing, 2021 We consider the problem of reconstructing a signal from under-determined modulo observations (or measurements). This observation model is inspired by a relatively new imaging mechanism called modulo imaging, which can be used to extend the dynamic range ...

Computational single-image high dynamic range imaging
, 2018 This thesis proposes solutions for increasing the dynamic range (DR)—the number of intensity levels—of a single image captured by a camera with a standard dynamic range (SDR). The DR in a natural scene is usually too high for SDR cameras to capture, even with optimum exposure settings.

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
