動き推定の容易化

Title:

動き推定の容易化

Document Type and Number:

Japanese Patent JP4197434

Kind Code:

B2

Abstract:

An apparatus and method for facilitating a subsequent choice of a motion vector from a plurality of candidate motion vectors in a motion estimation method, include receiving video image data from first, second and third consecutive groups ( 10, 20, 30 ) of image data. A first image part ( 12 ) of the first group of image data ( 10 ), a second image part ( 22 ) of the second group of image data ( 20 ), and a third image part ( 32 ) of the third group of image data ( 30 ) are identified, wherein the positions of the three image parts ( 12, 22, 32 ) correspond to a motion trajectory that is indicated by a candidate motion vector. A first error measure is then calculated by testing for differences between the first image part ( 12 ) and the third image part ( 32 ) and quantified as a first error measure. A second error measure is calculated by testing for differences between either the first image part ( 12 ) and the second image part ( 22 ) or the second image part and the third image part and quantified as a second error measure. An output error measure is then quantified, wherein the output error measure is derived from either the first or the second or a combination of both error measures.
