在本节中,我们将演示如何使用 scikit image 的形态学模块中的函数来实现一些形态学操作,首先对二值图像进行形态学操作,然后对灰度图像进行形态学操作。 二进制运算 让我们从二值图像的形态学操作开始。在调用函数之前,我们需要创建一个二进制输入图像(例如,使用具有固定阈值的简单阈值)。 腐蚀 侵蚀是一种基本的形态...

L = R * 299/1000 + G * 587/1000 + B * 114/1000在把图像转换为二值图(bilevel image)(模式“1”)时,源图像首先被转换为黑白图。然后在结果中,值大于127的像素点被设置为白色,图像抖动(and the image is dithered)。使用point方法可以改变阈值。

The Image module provides a class with the same name which is used torepresent a PIL image. The module also provides a number offactory functions(including functions toload images from files, and tocreate new images) 图像对象 Image– from file or newly created ...
