  • Method and system for spatial-temporal denoising and demosaicking for noisy color filter array videos
    Patent number: 8345971
    Abstract: A method for spatial-temporal denoising and demosaicking for noisy color filter array (CFA) video, the method including applying spatial-temporal CFA video denoising (11) to the CFA video in order to generate a denoised CFA, applying initial color demosaicking (CDM) (19) to the denoised CFA video in order to generate a demosaicked video, and applying spatial-temporal post-processing (26) to the demosaicked video in order to reduce CDM artifacts and CDM errors and enhance the quality of the video.
    Type: Grant
    Filed: June 28, 2010
    Date of Patent: January 1, 2013
    Assignee: The Hong Kong Polytechnic University
    Inventors: Lei Zhang, Weisheng Dong, Hainlong Zhu
