  • Patent number: 9251554
    Abstract: Signal flows for data-processing applications may be implemented so as to enable each processing node in the flow when it contains a sufficient amount of input data at its input buffer. In various embodiments, such signal flows can be graphically defined in a GUI tool which, thereafter, auto-generates suitable code for implementing the signal flow.
    Type: Grant

  • Publication number: 20140241636
    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.

  • 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.

  • Patent number: 8406303
    Abstract: A method and apparatus utilizing a prediction guided decimated search motion estimation algorithm are provided. The prediction guided decimated search motion estimation algorithm generates a motion vector used to encode a macroblock in a frame from a video sequence. The algorithm includes generating full-pixel seed vectors, performing a full-pixel search around the generated seed vectors, which is followed by a fractional pixel search. The full-pixel seed vectors generated are a predicted motion vector and a hierarchical motion vector. A fractional pixel search may be conducted around a final motion vector generated by the full-pixel search and may include a half-pixel search and a quarter-pixel search. The prediction guided decimated search motion estimation algorithm can be implemented in both software and hardware. The algorithm is characterized by improved efficiency, scalability, and decreased complexity.
