  • Patent number: 8675080
    Abstract: Motion estimation systems and methods are disclosed. An apparatus may include a processing unit to acquire video images and to arrange the video images into a plurality of sequential video frames, and a motion estimation unit that receives the sequential video frames and determines a set of repetitive pattern neighbor candidate vectors for repetitive pattern content in a first frame. The set of repetitive pattern neighbor candidate vectors may be reduced by sorting the set to eliminate spurious repetitive pattern neighbor candidate vectors. The reduced set may be provided to a second adjacent frame. A method may include acquiring a plurality of sequential video frames having a repetitive pattern content, and determining a set of repetitive pattern neighbor candidate vectors for the repetitive pattern content in a first frame of the sequential video frames. The set of repetitive pattern neighbor candidate vectors may be sorted by determining at least one spurious repetitive pattern neighbor candidate vector.

  • Publication number: 20120113326
    Abstract: The present disclosure provides a system and method for detecting motion vectors in an image frame using a recursive hierarchical process with a non-rasterized vector-scanning motion to reduce erroneous motion vectors in an image frame of a digital video sequence. In general, a resolution hierarchy is generated for an image frame, wherein the resolution hierarchy comprises the original image frame and one or more copy image frames each having a different, lower resolution than the original image frame. Each image frame in the hierarchy is partitioned into image patches disposed in columns and rows, and the image patches are scanned in a non-rasterized motion to detect motion vectors in each image patch. The disclosed system and method provides faster convergence and improved accuracy by converging motion vectors in multiple directions and minimizing erroneous motion vectors in the image sequence.

  • Patent number: 7158186
    Abstract: A video display system is disclosed. The video display system comprises a display generator for providing a display timing signal and a frame rate converter for receiving input video data, input video timing, and for providing output video data. The system includes a control logic for receiving a frame rate indication signal, the video input timing and the display timing signal. The control logic changes the display frame rate of the display generator in accordance with the native frame rate of the program, and in such a way as to maintain a stable image throughout.
