multiscale edges的用法和樣例：
例句
- Multiscale edges of a signal can be detected by using extrema or zero-crosings of dyadic wavelet transform.
本文通過二進小波變換極值或零交叉點可獲取信號的多尺度邊緣，由此得到信號的絕大部分信息。 - In order to detect edges correctly while noise can be effectively restrained, wavelet multi-scale edge detection method with signal registration technology was proposed.
摘要為了在準確檢測邊緣的同時有效地抑制雜訊，提出了結合信號配准技術的小波多尺度邊緣檢測方法。
