  • Publication number: 20110206127
    Abstract: Methods and an apparatus for interpolating a digital image frame located between a first anchor frame and a second target frame are described. The apparatus comprises a motion vector estimator unit for estimating a block-based motion vector and a corresponding variable-size sub-block motion vector based on, and between, the first anchor frame and the second target frame; and a motion compensation interpolation unit for interpolating the digital image frame from the corresponding variable-size sub-block motion vector.

  • Patent number: 7860167
    Abstract: An efficient and non-iterative 3D post processing method and system is proposed for mosquito noise reduction, block localization and correction in DCT block-based decoded images. The 3D post processing is based on a simple classification that segments a picture in multiple regions such as Edge, Near Edge, Flat, Near Flat and Texture regions. The proposed technique comprises also an efficient and shape adaptive local power estimation for equivalent additive noise and provides simple noise power weighting for each above cited region. Temporal filtering configurations using Minimum Noise Variance Criterion are proposed for reducing temporally varying coding artifacts. A Minimum Mean Square Error or Minimum Mean Square Error-like noise reduction with robust and effective shape adaptive windowing is utilized for smoothing mosquito and/or random noise for the whole image, particularly for Edge regions.

  • Patent number: 7545391
    Abstract: The present description discloses a method for resizing an input image having input pixels. The method comprises segmenting the input made into region types by assigning one of the region types to each one of the input pixels; and interpolating the input image according to the region type assigned to each one of the input pixels to produce a resized image having interpolated pixels.
