Object region information describing the method and object region information generation apparatus and image processing method and image information processing apparatus

摘要

PROBLEM TO BE SOLVED: To provide an object area information describing method capable of describing a desired object in video data is a small data amount and facilitating preparation and handling of these data as well. SOLUTION: Concerning the object area information describing method for describing object area data expressing objects 204-205 in video data 201-203, target object areas 205 and 206 are expressed using a conversion parameter showing area conversion from the reference object area 204 to the relevant target object areas 205 and 206, concerning each of conversion parameters, a locus at the time of arranging this conversion parameter along with the progress of a frame is approximated with a prescribed approximate function and concerning each of conversion parameters, the object area data related to the area of the object are described using an approximate function parameter for specifying the prescribed approximate function and this reference object area.
