High dynamic range video merging, tone mapping, and real-time implementation
… image. The second contribution is a method of tone mapping HDR video which solves potential problems of HDR video flicker and automated parameter control of the tone mapping operator. A prototype of this HDR video capture technique along with the combining and tone mapping algorithms have been …

The phonetics and phonology of tone mapping in a constraint-based approach
… both phonetic and phonological aspects of tone mapping in various Chinese languages. The central issue addressed is the role of contrast and positional prominence and neutralization in the realization of tone. The inventory of tonal contrasts constrains the outputs of contextual …

Towards an Improved Hardware Implementation of a Tone Mapping Algorithm for Wide Dynamic Range Image Display
Tone mapping algorithms are utilized to adapt wide dynamic range (WDR) images to limited dynamic range (LDR) displays while maintaining the images’ details. This thesis presents an analog current mode implementation that will realize an exponent-based tone mapping algorithm, including both global …

Exploring the visualisation of the cervicothoracic junction in lateral spine radiography using high dynamic range techniques
… to high dynamic range (HDR) processing and tone mapping. A shoulder girdle phantom was constructed using Perspex, shoulder girdle and vertebral bones and water to reproduce the attenuation caused by soft tissue. The design allowed for the removal of the shoulder girdle in order for the …

Proposal of Architecture and Circuits for Dynamic Range Enhancement of Vision Systems on Chip designed in Deep Submicron Technologies
… rango dinámico. Esto se denomina Mapeo de Tonos (Tone Mapping) y usualmente emplea solo 8-bits/píxel para las representaciones de imágenes, ya que éste es el estándar para las imágenes de bajo rango dinámico. Los píxeles de adquisición compresiva, por su parte, realizan una compresión que no es …

Snímání obrazu s vysokým dynamickým rozsahem
Bakalářská práce se zabývá základními principy zvyšování dynamického rozsahu u digitální fotografie. Práce dále hledá, jaké metody se využívají pro vytvoření fotografie s vysokým dynamickým rozsahem (HDR) a prozkoumává metody pro kompresi HDR obrazu pro zobrazení na zařízeních s nízkým dynamickým …
