Título: | High-dynamic range tone-mapping algorithm for focal plane processors |
Autor: | Vargas-Sierra, S. CSIC ORCID; Liñán-Cembrano, G. CSIC ORCID ; Roca, Elisenda CSIC ORCID ; Rodríguez-Vázquez, Ángel CSIC ORCID | Fecha de publicación: | 2011 | Editor: | The International Society for Optics and Photonics | Citación: | V Bioelectronics, Biomedical, and Bioinspired Systems ; and V Nanotechnology (2011) | Serie: | Proceedings of SPIE 8068 | Resumen: | This paper presents a Dynamic Range improvement technique which is specially well-suited to be implemented in Focal Plane Processors (FPP) due to its very limited computing requirements since only local memories, little digital control and a comparator are required at the pixel level. The presented algorithm employs measurements during exposure time to create a 4-bit non-linear image whose histogram determines the shape of the tone-mapping curve which is applied to create the final image. Simulations results over a highly bimodal 120dB image are presented showing that both the highly and poorly illuminated parts of the image keep a sufficient level of details. | Descripción: | Comunicación presentada al "V Bioelectronics, Biomedical, and Bioinspired Systems V and Nanotechnology" celebrado en Praga (República Checa) del 18 al 20 de Abril del 2011. | Versión del editor: | http://dx.doi.org/10.1117/12.889448 | URI: | http://hdl.handle.net/10261/84563 | DOI: | 10.1117/12.889448 | Identificadores: | doi: 10.1117/12.889448 isbn: 9780819486578 |
