Abstract:
1. An image predictive encoding apparatus, comprising: a region dividing means for dividing an input image into a plurality of regions; a prediction signal generating means for generating a prediction signal for an object pixel signal of an object region which is a processing object, of the plurality of regions divided by the region dividing means; a residual signal generating means for generating a residual signal between the prediction signal generated by the prediction signal generating means and the object pixel signal; and an encoding means for encoding the residual signal generated by the residual signal generating means; wherein the prediction signal generating means comprises: a prediction related information generating means for generating, as prediction related information, a method for generating a signal having a high correlation with the object pixel signal of the object region from an already reproduced signal; and a texture synthesis means for generating a prediction signal for the object region on the basis of the prediction related information generated by the prediction related information generating means; the texture synthesis means generates a template signal of a specified region which is determined on the basis of the prediction related information, from the already reproduced signal, searches a pre-determined reproduced image to find a plurality of similar regions having a high correlation to the specified region, generates a plurality of texture signals relating to the object region on the basis of the plurality of similar regions, and generates a prediction signal by processing the plurality of texture signals by using a pre-determined texture synthesis method; and the encoding means encodes the prediction related information generated by the prediction related information generating means.
