On most of the simulators, you'll notice that rotating the viewport causes the image to be scaled out to match the new 480-pixel width of the device.

在大多数模拟器中，您将注意到旋转视窗后将向外扩展图像以匹配设备的480像素的新宽度。

Morphological watershed transform is a mathematical morphology image segmentation method. It can access an accurate verge. That is continuous, closed single-pixel width verge.

形态学分水岭变换是一种数学形态学图像分割方法，它可以得到精确的边缘，即连续、封闭、单象素宽的边缘。

This paper introduces the double-structure element edge detection algorithm base on morphology edge. This algorithm provides a new morphological operator to detect single pixel width edge in an image.

由此，可以根据这些性质建立类似一般性的差分算子的形态差分算子来进行边缘检测。
