1) second-order predict
二阶预测
1.
To reduce the data size of CAD product model,we presented an algorithm to compress the B-spline curves and surfaces based on second-order prediction in local coordinate system.
提出一种局部坐标系下二阶预测编码算法,对B样条控制网格构造局部坐标系,在局部坐标系下对控制点进行一阶预测,对相邻控制点一阶预测误差再进行二阶预测,对二阶预测误差量化后进行算术编码。
2) second-order prediction
