例句
- Especially in the edge extraction, the speckle noise makes none of the conventional extraction algorithms get good result.
特別是對于邊緣提取，斑點(diǎn)噪聲使得傳統的提取算法幾乎都無(wú)法取得理想的效果。 - Combined with pattern matching, this new method could increase the precision of transferring the result of edge extraction from one slice to another.
結合匹配技術(shù)，提高邊緣提取結果層間傳遞的精度。
