CHARACTERISTIC SCALING DEVICE, CHARACTERISTIC POSITIONING ASSESSMENT SYSTEM, CHARACTERISTIC POSITIONING METHOD AND CHARACTERISTIC POSITIONING PROGRAM

摘要

A feature point position estimation device is provided. The feature point position estimation apparatus includes an object detection section (11) for detecting a subject area from a subject image, a feature point positioning section (12) for positioning a feature point at a previously prepared initial feature point position with respect to the subject area, a feature amount acquisition unit (13) for detecting a feature amount of the arranged feature points a regression calculation unit (14) for calculating a deviation amount of a position of a true feature point with respect to the position of the feature point by performing a regression calculation on the feature amount and a repositioning unit (16) for repositioning the feature points based on the deviation amount. The regression calculation unit calculates the deviation amount by converting the feature amount into a matrix-resolved regression matrix.
