Claim:
1. A posture estimation apparatus that estimates a paired part based on an image including a whole or part of an articulated object having the paired part, the posture estimation apparatus comprising a processor configured to: extract a plurality of candidate regions of the paired part from the image using a common feature value indicating features of a shape common to an indefinite number of articulated objects regarding the paired part; extract a first candidate region having a maximum likelihood of being the paired part from the plurality of candidate regions and designates a region other than the first candidate region as a second candidate region; calculate a unique feature value indicating a feature unique to the articulated object to be estimated about the paired part in each of the first candidate region and the second candidate region; correct a unique feature value of one of the first candidate region and the second candidate region based on at least one of a length, width, and angle of the other candidate region; and determine whether or not the first candidate region and the second candidate region are the paired parts based on similarity between the corrected unique feature value and a unique feature value of the other candidate region.
