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. 由于圖像的奇異值特征具有良好的穩定性，可以將奇異值當作一種有效的代數特征來(lái)描述并表征圖像。
The algorithm uses the obtained grey value characteristic point as the searching foundation, which is different from the traditional ergodic search strategy. 該算法利用得出的灰度值特征點(diǎn)作為搜索依據，改變了傳統匹配方法遍歷性質(zhì)的搜索策略。
