Instead of using the traditional nonlinear l space  the proposed method transfers the color distribution of the target image (daylight color image) to the source image (fused multiband nighttime imagery) in the linear YCBCR color space. The YCBCR transformation is simpler and more suitable for image fusion compared to the l conversion. The YCBCR transformation can be extended into a general formalism. And the paper mathematically proves that  for color transfer  using color spaces conforming to this general YC BCR space framework can produce same recoloring results as using the YCBCR space. Experimental results demonstrate that the YCBCR based color transfer method works surprisingly well for transferring natural color characteristics of daylight color images to false color fused multiband nighttime imagery  and moreover  can also be successfully applied to recoloring a variety of color images. 2010 SPIE.   Fast color-transfer-based image fusion method for merging infrared and visible images (EI CONFERENCE) 会议论文 Multisensor, Multisource Information Fusion: Architectures, Algorithms, and Applications 2010, April 7, 2010 - April 8, 2010, Orlando, FL, United states Li G.; Xu S.; Zhao X. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 We present a computationally efficient color image fusion algorithm for merging infrared and visible images. At the core of the proposed method is the color transfer technique based on the linear YCBCR space. The method directly uses the grayscale fused image and the difference signals of the input images to construct the source YCBCR components  then uses the statistical color transfer technique to form a color fused image that takes the target image's color characteristics. Two different strategies  which respectively employ the pixel averaging fusion scheme and the multiresolution fusion scheme as the grayscale image fusion solution  are proposed to fulfill different user needs. The simple strategy using the pixel averaging fusion scheme answers to a need of easy implementation and speed of use. And the complex strategy using the multiresolution fusion scheme answers to the high quality need of the fused products. In addition  we also describe some useful theories about color-transfer-based image fusion. Experimental results show that the proposed color image fusion algorithm can effectively produce a natural appearing "daytime-like" color fused image  and even using the pixel averaging fusion scheme to implement the grayscale fusion can also provide a pleasing result. 2010 Copyright SPIE - The International Society for Optical Engineering.   System of Facial Detection and Location Based on Integrated Technology 会议论文 International Conference on Future Computer and Communications (ICFCC 2009), 2009 作者:  Wang Juhui 收藏  |  浏览/下载：3/0  |  提交时间：2019/12/31 light compensation  YCbCr color space  gradient structure  canny edge  operator  weighted templates  projection   Automatic extraction of positive cells in tumor immunohistochemical pathology image based on YCbCr 会议论文 作者:  Liu, Binghan;  Wang, Weizhi 收藏  |  浏览/下载：0/0  |  提交时间：2019/11/26 automatic extraction  YCbCr color space  positive cells  pathology images
