在图像处理中形状描述通常是一件比较困难的事情，这本书用Morphological的方法对形状进行描述，以便于进一步进行图像的模式识别和理解。-The computer descr iption of shape and the computer manipulation of shape is complex simply

because shape itself is complex. Of course, if the world of shape were limited to the Euclidean

shapes, there would be no such complexity. However, shape includes all the varieties of biological

shapes: from the shapes of trees and their leaves to fish, animals, flowers, and plants –

and also natural shapes, such as those of coastlines, and of rocks and crystals.
