  • Denoising images with a color matrix pyramid
    Patent number: 9049334
    Abstract: A method for chroma denoising a digital image created in a digital camera includes decomposing the digital image into a plurality of spatial frequency bands. A separate modified color correction matrix is calculated from a color correction matrix associated with the camera for each of the plurality of spatial frequency bands. Each modified color correction matrix is applied to data in its corresponding spatial frequency band to produce color-corrected data in the plurality of spatial frequency bands. The color-corrected data in plurality of spatial frequency bands is combined to produce an output image.

  • Method for detecting pixel outliers
    Patent number: 8559730
    Abstract: A method for identifying singleton outlier pixels in a selected color space in a digital image including a plurality of pixels, includes for each 3×3 patch of pixels in the image, calculating the diameter of the 3×3 patch of pixels. For each pixel in the patch, the distance to its nearest neighbor pixel within the patch is computed, as measured in the selected color space. The computed distance from each pixel in the patch is compared to its nearest neighbor with a threshold that is a preselected fraction of the diameter. A center pixel in the patch is identified as an outlier pixel if its calculated distance to its nearest neighbor is the largest distance to a nearest neighbor and exceeds the threshold.
