  • System and method for removing image noise
    Patent number: 9563938
    Abstract: A system and method for removing noise from images are disclosed herein. An exemplary system includes an edge-detection-based adaptive filter that identifies edge pixels and non-edge pixels in an image and selects a filtering technique for at least one non-edge pixel based on a comparison of the at least one non-edge pixel to a neighboring pixel region, wherein such comparison indicates whether the at least one non-edge pixel is a result of low-light noise.
    Type: Grant
    Filed: May 5, 2014
    Date of Patent: February 7, 2017
    Assignee: Analog Devices Global

  • Component filtering for low-light noise reduction
    Patent number: 8755625
    Abstract: In general, in one embodiment, low-light noise is removed from an image by separately filtering luma and chroma components of the image, by adaptively filtering the image based at least in part on a Gaussian distribution of the image, and/or by dividing the image into separate regions and filtering each region separately.
