    摘要: A feature value extraction apparatus, a method, and a program capable of extracting local feature values whose positions are unchanged, and a place estimation apparatus, a method, and a program equipped with them are provided. A place estimation apparatus (10) performs a place estimation process by using position-invariant feature values extracted by a feature value extraction unit (11). The feature value extraction unit (11) includes local feature value extraction means (21) for extracting local feature values from each of input images formed from successively-shot successive images, feature value matching means (22) for obtaining matching between successive input images based on the extracted local feature values, corresponding feature value selection means (23) for selecting matched feature values as corresponding feature values, and position-invariant feature value extraction means (24) for obtaining position-invariant feature values based on the corresponding feature values. The position-invariant feature value extraction means (24) extracts, from among the corresponding feature values, corresponding feature values whose position change is equal to or less than a predetermined threshold as the position-invariant feature values.
