Abstract:
A property information encoder for encoding property information of a two or three dimensional mesh object, comprising:a quantizer for quantizing input property information; a predictor for predicting currently input property information; a selector for selecting either a prediction value output from the predictor or a predetermined value according to an operating mode input by user, and outputting the selected value; a subtracter for subtracting a value output from the selector from a value output by the quantizer; and an encoder for compressing information of a prediction error signal output by the subtracter, wherein the selector operates in either a selection mode of selecting either a prediction value output from the predictor or a predetermined value according to a measured characteristic of said input property information, and outputting the selected value or a fixed mode for outputting a prediction value output by the predictor.
