例句
- The SVD had robust performance that was invariant to image disturbance and it made the singular value credible to represent the image as an algebraic feature.
由于图像的奇异值特征具有良好的稳定性，可以将奇异值当作一种有效的代数特征来描述并表征图像。 - The algorithm uses the obtained grey value characteristic point as the searching foundation, which is different from the traditional ergodic search strategy.
该算法利用得出的灰度值特征点作为搜索依据，改变了传统匹配方法遍历性质的搜索策略。
