摘要： When a randomly-accessible inter picture is encoded, a prediction image generator sets a reference picture from among a plurality of randomly-accessible intra pictures, and performs a motion-compensated prediction using the set reference picture for a prediction process, and a variable length encoding unit 13 encodes both picture position information showing the position of the reference picture, and identification information showing that the randomly-accessible inter picture is randomly accessible, and multiplexes encoded data about both the picture position information and the identification information into a bitstream.

摘要： An apparatus to decode an encoded bit stream obtained by dividing the moving image into a plurality of rectangular regions includes a rectangular region size determination unit for determining a variable size of the regions in a sequence (a set of continuous frames) based on region size information multiplexed in the encoded bit stream. The apparatus includes a decoding unit for decoding coding mode information multiplexed in the encoded bit stream for each of the regions, and a decoding unit. The coding mode information includes (1) prediction type information selected from information indicating either inter or intra prediction coding, and (2) intra prediction block size information indicating a size of a unit region for the intra prediction coding indicated by the prediction type information.

摘要： A congestion degree estimating unit (12) which estimates, for each image frame, a congestion degree of an area in which each object detected by an object detecting unit (11) is present is provided. An object selecting unit (13) refers to an estimation result of the congestion degree by the congestion degree estimating unit (12) for each image frame, and selects an object present in an area the congestion degree of which is equal to or lower than a first threshold out of one or more objects detected by the object detecting unit (11).

摘要： An image feature map generating unit (3) generates, on the basis of feature amounts extracted from a plurality of images successively captured by a camera (109), an image feature map which is an estimated distribution of the object likelihood on each of the images. An object detecting unit (4) detects an object on the basis of the image feature map generated by the image feature map generating unit (3).

摘要： A loop filter unit 11 carries out a class classification of a local decoded image generated by an adding unit 9 into one class for each coding block having a largest size determined by an encoding controlling unit 2 and also designs a filter that compensates for a distortion piggybacked for each local decoded image belonging to each class, and also carries out a filtering process on the above-mentioned local decoded image by using the filter. A variable length encoding unit 13 encodes, as filter parameters, the filter designed by the loop filter unit 11 and used for the local decoded image belonging to each class, and a class number of each largest coding block.
