| Abstract: | A multi-channel circular spatial filter (MCSF)
in YCbCr-color space is developed for color image
denoising. In [2], Bhoi and Meher proposed and
demonstrated that circular spatial filter performed very
well for efficient suppression of additive white Gaussian
noise (AWGN) from gray images. Here multi-channel
versions of the circular spatial filter are proposed and
developed. The developed filter is based on three-channel
processing (e.g., RGB-processing, YCbCr-processing,
etc.). The YCbCr version of MCSF is observed to yield
quite superior performance as compared to the other
versions in RGB, CMY and CIE Lab color spaces. The
proposed filter outperforms the multi-channel versions of
existing filters in terms of objective and subjective
evaluation measures. |
