本文讨论了一种新的基于双结构元的自适应形态学运算，并将其应用于超声散斑图像的边界增强。DSE是两种不同结构元素的组合。DSE产生边缘锐化效果，随着输入图像的局部特征而变化。一般的单个结构元素不具有锐化功能。我们的方法提高了组织边界周围的对比度，而没有斑点强调，并且不会在边界周围产生过冲或下冲。我们证明了它的有效性，在实验中使用乳腺癌图像。
We discuss new adaptive morphological operations using double structuring elements (DSEs) and apply them to boundary enhancement of ultrasound B-mode images with speckle pattern. The DSE is a combination of two different structuring elements. The DSE yields an edge-sharpening effect, changing with the local characteristics of the input image. A general single structuring element does not have the sharpening function. Our method improves contrast around the tissue boundary without speckle emphasis and does not generate overshoot nor undershoot around the boundary. We demonstrate its effectiveness in experiments using breast cancer images.
