Moving object segmentation of motion image and its motion estimation method

摘要

The present invention relates to a method of accurately segmenting an image by a moving object unit and accurately estimating a motion of a moving object. To this end, the present invention is used in an object-oriented analysis-synthesis encoder and includes a moving object included in a current frame through multi-stage segmentation. 10. A method for dividing and describing the motion of a moving object as a set of motion parameters, the method comprising: (a) detecting a motion region of the current frame; (b) generating a motion vector field of the motion region; (c) a first division step of dividing the motion vector field using a two-dimensional translational motion model described by two motion parameters; (d) a second dividing step of dividing the results of the first dividing step using a planar motion model described by six motion parameters; (e) a third dividing step of dividing the result of the second dividing step using a curved motion model described by twelve motion parameters.
