摘要： PROBLEM TO BE SOLVED: To provide a code book preparing method capable of performing highly efficient vector quantization of high-dimensional texture data.
SOLUTION: In the method for preparing a code book by using a training vector generated from high-dimensional texture data acquired by photographing a subject under a plurality of photographing conditions, the photographing conditions are recorded when the texture data are acquired (S101), a cluster to which the training vector belongs is found out(S104), the center of gravity of a vector obtained by weighting the training vector by weight determined in accordance with the photographing conditions is found out as a new representative vector of the cluster to which the training vector belongs (S105), and the total error of new representative vectors of all clusters is evaluated on the basis of an error (S106). Whether the preparation of the code book is converged or not is judged from the transition of the total error (S107) and the processing of the steps S104-S106 is repeated until the convergence is judged.

摘要： PROBLEM TO BE SOLVED: To obtain a multi-viewpoint image encoding method by which precision in model information is enhanced without increasing the processing amount and which makes multi-viewpoint image with high quality transmittable. SOLUTION: The multi-viewpoint image encoding method is the one for generating an encoding stream by multiplexing encoded model information which is generated by making a subject into a model and prediction error information of a prediction signal which is generated from model information against respective viewpoint images. In this case, the shape of the subject is estimated (step 802). An angle made by a normal direction from the area of a subject surface and the direction of line of sight is obtained at every block concerning the respective viewpoint images based on the estimated shape, the angle is judged with threshold and a model block to be adopted as the model (step 803). The coordinates in three-dimensional space of representative points in the model block are calculated based on the estimated shape (step 804). Information on the luminance of the model block and information on the calculated coordinates are encoded and, then, model information is generated (step 805).
