Improved color reproduction based on CIELAB color space in integrated multi-scale retinex

Wang-Jun Kyung, Tae-Hyoung Lee, Cheol-Hee Lee, Yeong-Ho Ha, Reiner Eschbach, Gabriel G. Marcu, Shoji Tominaga, Alessandro Rizzi
2009 Color Imaging XIV: Displaying, Processing, Hardcopy, and Applications  
Accordingly, this paper proposes an enhanced IMSR method in a device-independent color space, CIELAB, to preserve hue and obtain high contrast and naturalness.  ...  This method is especially used to provide the proper luminance so that captured images give the same sensation as the scene. As a result, we can get high contrast and naturalness of colors.  ...  In the latest papers, IMSR (Integrated multi-scale Retinex) algorithm introduced a novel method to improve a visibility in dark shadow areas of natural color images while preserving pleasing contrast without  ...

ASSORTATIVE MATING PREFERENCES AMONG HYBRIDS OFFERS A ROUTE TO HYBRID SPECIATION

Maria C. Melo, Camilo Salazar, Chris D. Jiggins, Mauricio Linares
2009 Evolution  
These hybrids show assortative mating preferences, showing a strong preference for their own color pattern over that of either parental species.  ...  Second, once established such a lineage would inherit assortative mating preferences that would lead to partial reproductive isolation from parental lineages.  ...  Banco de la República grant 2297, Los Andes University science faculty, and Fondo Colombiano de Invesigaciones Cientificas y Proyectos Especiales Francisco Jose de Caldas COLCIENCIAS grant 120440520138 for  ...

Chromatic calibration of an HDR display using 3D octree forests

Jing Liu, Nikolce Stefanoski, Tunc Ozan Aydin, Anselm Grundhofer, Aljosa Smolic
2015 2015 IEEE International Conference on Image Processing (ICIP)  
We show that our method achieves high color reproduction accuracy through both objective metrics and a controlled subjective study.  ...  In this paper, we first characterize the image reproduction capability of a state-of-art HDR display through a set of measurements, and present a novel calibration method that takes into account the variation  ...  We model the HDR display's color reproduction by a mapping D : Gi → Go, ci → co (1) which receives input colors ci as input, and reproduces output colors co.  ...

Saliency driven Black Point Compensation

Albrecht Lindner, Nicolas Bonnier, Sabine Süsstrunk, Reiner Eschbach, Gabriel G. Marcu, Alessandro Rizzi
2011 Color Imaging XVI: Displaying, Processing, Hardcopy, and Applications  
We present a novel framework for automatically determining whether or not to apply black point compensation (BPC) in image reproduction.  ...  We find that our algorithm is correctly able to predict the observers' preferences in all cases when the saliency maps are unambiguous and accurate.  ...  The observers were asked to indicate for each image which reproduction they prefer: with enabled or disabled BPC.  ...

Visual sensitivity correlated tone reproduction for low dynamic range images in the compression field

Geun-Young Lee, Sung-Hak Lee, Hyuk-Ju Kwon, Kyu-Ik Sohng
2014 Optical Engineering: The Journal of SPIE  
An image toning method for low dynamic range image compression is presented. The proposed method inserts tone mapping into JPEG baseline instead of postprocessing.  ...  Subsequently, a luminance-adaptive tone mapping based on the human visual sensitivity properties is applied.  ...  To correct this chronic defect of tone mapping, we adopt a simple method for color compensation which restores a ratio of color to luminance before tone mapping. 30 This method is given by Cb 0 ¼ μG  ...
