MEASUREMENT-TARGET-SELECTING DEVICE, FACE-SHAPE-ESTIMATING DEVICE, METHOD FOR SELECTING MEASUREMENT TARGET, AND METHOD FOR ESTIMATING FACE SHAPE

WIPO Patent Application WO/2013/088672

A1

A measurement-target-selecting device that is capable of estimating, with high precision and at low computational time, a face shape that has undergone a three-dimensional change of expression, which is difficult to detect using only a two-dimensional image. In this device, a face texture assessment value calculating part (103) calculates a face texture assessment value representing a degree of matching between an input face image and the texture of a face shape candidate for each of a plurality of face shape candidates, a facial-expression-change-likelihood-calculating part (104) calculates a first likelihood between a face shape constituting a reference and a face shape candidate for each of the plurality of face shape candidates, a correlation assessment part (105) calculates a first correlation assessment value representing the strength of a correlation between the face texture assessment value and the first likelihood for each of the plurality of face shape candidates, and a selection part (107) selects from among the plurality of face shape candidates as a measurement target a face shape candidate having a first correlation assessment value that is lower than a first threshold.
