| titleOfInvention | Method and apparatus for coordination of motion determination over multiple frames |
| abstract | The present invention concerns improved motion estimation in signal records. A method for estimating motion between one reference image and each frame in a sequence of frames, each frame consisting of a plurality of samples of an input signal comprises the steps of: (1) for each frame, estimating a motion field from the reference image to the frame, (2) for each frame, transforming the estimated motion field into a motion matrix, where each row corresponds to one frame, and each row contains each component of motion vector for each element of the reference image, (3) performing a Principal Component Analysis on the motion matrix, thereby obtaining a motion score matrix consisting of a plurality of column vectors called motion score vectors and a motion loading matrix consisting of a plurality of row vectors called motion loading vectors, such that each motion score vector corresponds to one element for each frame, such that each element of each motion loading vector corresponds to one element of the reference image, such that one column of said motion score matrix and one motion loading vector together constitute a factor, and such that the number of factors is lower than or equal to the number of said frames, (4) for each frame, multiplying the motion scores corresponding to the frame by the motion loading vectors, thereby producing a motion hypothesis for each frame, (5) for each frame, estimating a motion field from the reference image to said frame, using the motion hypothesis as side information, outputting the motion fields estimated in step (5) representing the motion between said reference image and each frame in the sequence of frames. |
