FEATURE VECTOR COMPUTING DEVICE, FEATURE VECTOR COMPUTING METHOD, AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To reflect a color with a low color component value appropriately on a feature vector. PSOLUTION: A feature vector computing section 18 computes a value of a predetermined increase function on a color component value of at least partial elements out of components of an image, as at least one component of the feature vector of the image, and computes a value of a predetermined decrease function on the color component value of the at least partial elements as at least another component.
