An evaluation device for evaluating coding quality of coded data of an image for a first viewpoint in a multi-viewpoint image, the evaluation device includes an evaluation unit that evaluates coding quality of coded data relating to the first viewpoint by associating a pixel value of an original image for the first viewpoint, a pixel value obtained from the coded data relating to the first viewpoint, a pixel value of an original image for a second viewpoint that is different from the first viewpoint and a pixel value obtained from coded data relating to the second viewpoint with one another.

Evaluation apparatus, evaluation method and program

A prediction device for predicting a motion vector of a coding target block in coding of a composite image formed by combining multiple viewpoint images includes: a storage unit that stores a first predicted motion vector indicating a predicted motion vector candidate; and an update unit that if a predetermined condition is met, generates a second predicted motion vector that is a vector indicating a pixel in an adjacent viewpoint, the pixel being located at a position that is same as a position of the coding target block, and stores the second predicted motion vector the storage unit.

Prediction apparatus, prediction method and program

A position determination apparatus for determining, from a first image that is an image including at least a desired first subject, a position of the desired first subject, includes: a feature amount acquisition unit that acquires a first feature amount representing a predetermined feature of the first image; an estimation unit in which a second feature amount representing the predetermined feature obtained from a second image including a second subject is associated with a selected feature map that is a feature map corresponding to the second subject among a plurality of feature maps that are a set of feature maps that are maps representing features of the second image; an estimated first feature map that is estimated by the estimation unit to be associated with the first feature amount: and a position determination unit that determines the position of the desired first subject using the estimated first feature map.
