  • Fast noise reduction in digital images and video
    Patent number: 8139650
    Abstract: Presented are embodiments for nonlocal mean filtering that provide a robust and efficient method for reducing noise in digital images and video frames. These embodiments build on a separable property of neighborhood filtering to offer a fast, parallel and vectorized implementation in contemporary shared memory computer architectures while minimizing theoretical computational complexity. In practice, this approach is fast and scales linearly with image size.
    Type: Grant
