    摘要: A methodology and structure is described for processing a video signal comprising a plurality of fields. Each of the fields of the video signal are partitioned into a plurality of regions. Statistical measurements are then performed on each field to detect a field-level temporal periodic pattern and on each region within the fields to detect a region-level temporal periodic pattern. The regions in each field are then processed using the field-level temporal periodic pattern and the region-level temporal periodic pattern.

    摘要: A method and system for reducing crosstalk for a three dimensional display includes a processor in communication with a display configured to display three dimensional video. The processor is configured to determine a viewing angle between a section of the three dimensional display and a viewpoint of the three dimensional display, generate a crosstalk compensation function for the section of the three dimensional display, wherein the crosstalk function compensates for the crosstalk at the viewing angle, and apply the crosstalk compensation function to the section of the three dimensional display to reduce the crosstalk of the three dimensional display from the viewing angle.

    摘要: Systems and methods of motion compensated frame rate conversion are described herein. These systems and methods convert an input video sequence at a first frame rate to an output video sequence at a second frame rate through a novel motion estimation and motion vector processing stage that produces a motion field having a plurality of motion vectors that describe the movement of objects between input video frames from the perspective of an interpolated video frame. A subsequent motion compensated interpolation stage then constructs the interpolated video frame using an adaptively blended combination of a motion compensated prediction and a temporal average prediction of the pixel values from the input video frames. Motion estimation in these systems and methods is enhanced by utilizing spatial and temporal biasing on the predictions of moving objects between and within the input frames, and also by removing aberrational motion vectors from the motion field through a hierarchy of motion vector processing blocks.
