Abstract: An estimation unit estimates attitude parameters, which are parameters representing an attitude of an object in a target image based on the target image, which is an image in which the object whose attitude is to be estimated has been taken, using an attitude estimation model learned using one or more teacher data including a teacher image, which is an image in which the object has been taken, and the attitude parameters of the object in the teacher image. An acquisition unit acquires a teacher image whose attitude similarity, which is a degree of similarity between the estimated attitude parameters and the attitude parameters related to the teacher image, is the largest among one or more teacher images included in the one or more teacher data. A first computation unit computes an image similarity, which is a degree of similarity between the target image and the acquired teacher image.
