| 摘要 |
A computer system for real-time determination of a motion vector comprising an image processor to apply an image processing filter to a normalized frame element of a first image frame, yielding a filtered frame element having associated filtered pixel values, a pixel selector to select a first reference pixel from the filtered frame element having the highest value of the filtered pixel values, an optic flow module to determine a first optic flow applied at a location of the first reference pixel, a pattern matching module to perform pattern matching between the normalized pixel values of the normalized frame element and normalized frame elements of a second image frame, yielding a plurality of pattern matching scores, and a motion vector determiner to determine a motion vector based on a lowest one of the pattern matching scores. Related apparatus and methods are also described. |
