Abstract: A shape similarity computation unit (2021) computes, as a shape similarity, a similarity in shape between a learning movement path curve which is a movement path curve obtained through learning and an observation movement path curve which is a movement path curve obtained through observation. A position similarity computation unit (2022) computes, as a position similarity, a similarity in position between the learning movement path curve and the observation movement path curve when the learning movement path curve and the observation movement path curve are placed in a same coordinate space. A conformity computation unit (203) computes a conformity between the learning movement path curve and the observation movement path curve, using the shape similarity and the position similarity.

Abstract: An acquisition unit acquires a query feature quantity which is a collection of feature quantities for a query moving image and a feature quantity record which is a collection of feature quantities for a candidate moving image. A similarity map generation unit compares the query feature quantity with the feature quantity record, calculates a similarity between the query feature quantity and the feature quantity record for each of frames of the candidate moving image and generates a similarity sequence in which the similarities are chronologically arranged, and generates a similarity map in which the similarity sequences for the respective frames of the candidate moving image are arranged in order of the frames of the candidate moving image.

Abstract: An image encoding apparatus includes an image transformation unit which transforms an input image signal with a first resolution to a second image signal with a second resolution lower than the first resolution, a region acquisition unit which acquires an attention region of an image indicated by the input image signal, a region information output unit which outputs first region information indicating the attention region, a first encoding unit which acquires a partial region signal corresponding to the attention region from the input image signal and encodes the partial region signal to a first encoded signal, a second encoding unit which encodes the second image signal to a second encoded signal, and an output unit which outputs the second encoded signal and the first encoded signal.

Abstract: An image encoding apparatus continues displaying even if some image data is missing and can reduce delay in reverse reproduction. The image encoding apparatus subjects a picture at the head of a GOP (Group of Picture) to intra-frame prediction encoding and the other pictures to inter-frame prediction encoding, for the other pictures, the image encoding apparatus subjects either top fields or bottom fields to intra-frame prediction encoding in a forward direction with respect to a display order, and the other fields to inter-frame prediction encoding in a reverse direction with respect to the display order.

Abstract: According to an image encoding apparatus, an image analyzing apparatus, an image encoding method, and an image analyzing method, the image encoding apparatus, on carrying out encoding, outputs encoded data to which texture encoded data which is made by encoding an image and additional information encoded data which is made by encoding additional information including information necessary for analyzing the image data are multiplexed, and the image analyzing apparatus demultiplexes the additional information encoded data from the encoded data, decodes the additional information encoded data, and analyzes the additional information. The image analysis is performed without decoding the texture encoded data, and thus the computation quantity related to the decoding process of the encoded data can be reduced.
