使用形態(tài)學的思想進行圖像的邊緣檢測，提出了在一次形態(tài)處理中使用雙結構元的一系列一般性形態(tài)邊緣檢測算子和抗噪型形態(tài)邊緣檢測算子的算法，并給出算子的性質。新算子在使用同一對結構元處理中既具有定位能力又具有細節(jié)保留功能，抗噪型算子能很好地檢測出圖像的單像素寬的邊緣。

In the paper, we extend the definition of traditional image edge to morphology edge，derive a series of new morphological operators which are enlightened by semi-increasing and semi-continuation and first time bring forward double-structure element used in morphological processing at one time. These new morphological operators can resist noise and have good merit which not only have good location but keep image detail. Experiments have shown that better image edge detection results will be produced by these operators than otherwise by traditional methods, moreover, the edge thus detected is basically continuous with single-resolution-widths.
