17-8 ウェーブレット変換による形状データ圧縮における誤差の保証(第17部門画像符号化2)

Data compression by using the Discrete Wavelet Transform has a problem in that the errors caused by irreversible process. We propose an algorithm for limited error compression for CAD models. By using our method, the user can specify the maximum error before compressing the shape data.
