To find a high performance reduction algorithm is a focus point in the research on rough sets, but there doesn't exist an efficient method so far.
寻求一种高效的属性约简算法仍然是粗糙集的研究热点之一，现尚不存在一种非常有效的约简算法。
Parametric active contours represent their contours by the point sets or B-splines, and they have the efficient performance on image segmentation.
参数活动轮廓模型采用点集或B -样条曲线来表示模型的轮廓线，具有运算效率高的特点。
