摘要： An object of the present invention is to reduce the size of encoded feature descriptors. A feature descriptor encoding apparatus includes a feature point detection unit that detects feature points from an image and outputs coordinate values; a local feature descriptor extracting unit that extracts local feature descriptors from local regions centered on the coordinate values of the feature points; a coordinate value scanning unit that converts the coordinate values into index values according to a specific scanning method; a sorting unit that sorts the index values; a difference calculation unit that calculates a differential value between two adjacent index values of the sorted index values and outputs a sequence of differential values; a differential encoding unit that encodes the sequence of the differential values in a sequential permutation; and a local feature descriptor encoding unit that encodes the local feature descriptors of the corresponding feature points in the same permutation as that of the sorted index values.

摘要： A product registration apparatus (20) includes a comparison unit (22) and a registration unit (24). The comparison unit (22) compares a first frame and a second frame of a video. The second frame is generated at a time later than the first frame. The comparison unit (22) determines a product that is not included in the first frame but included in the second frame. Then, the registration unit (24) registers the determined product (product that is not included in the first frame but included in the second frame) as a payment target.
