A method for estimating the motion within a moving picture using a two-dimensional triangle-patch wireframe model, comprising the steps of dividing (200) the current frame of an input image signal into N 1 N 2 macroblock units, dividing (202) each of the macroblocks into two to create triangle patches, calculating (204) pixel differences between a reference block and search blocks of the previous frame in a predetermined range on the basis of the coordinate values of the respective apexes of the triangle patches, and calculating (206) a motion vector of the reference block of the current frame from the coordinate value of the matching block of the previous frame having a minimum pixel difference value among the calculated pixel differences. Thus, it is possible to obtain a picture of good quality compared with a picture reconstructed by the conventional BMA method for estimating the motion. |
