Denoising cfa images using weighted pixel differences |
| abstract |
A method for reducing noise in an image captured using a digital image sensor having pixels being arranged in a rectangular minimal repeating unit, comprising: computing first weighted pixel differences by combining first pixel differences between the pixel value of a central pixel and pixel values for nearby pixels of the first channel in a plurality of directions with corresponding local edge-responsive weighting values; computing second weighted pixel differences by combining second pixel differences between pixel values for pixels of at least one different channel in the plurality of directions with corresponding local edge-responsive weighting values; and computing a noise-reduced pixel value for the central pixel by combining the first and second weighted pixel differences with the pixel value for the central pixel. |
