Noise-reduction method and apparatus
A noise-reduction method and apparatus are provided. The noise-reduction method includes estimating activity levels of regions in an input image; and applying different weights to a large noise filter kernel and a small noise filter kernel according to the estimated activity levels, wherein the estimating includes calculating a noise level of the input image, generating a binary image by calculating signal-to-noise ratios (SNRs) of pixels of the input image and by comparing the SNRs of the pixels of the input image with a predefined threshold, and reducing binary data boundaries in the binary image.
