Python 什么是图像掩蔽？

在过去的几周里，我一直在用python学习图像处理。就在那时，我偶然发现了一个叫做“图像掩蔽”的术语。我参考了很多网站，但仍然找不到合适的解释。你能用一个例子解释一下什么是图像掩蔽吗？

有很多答案。这是一小份

is a process of graphics software like Photoshop to hide some portions of an image and to reveal some portions. It is a non-destructive process of image editing. Most of the time it enables you to adjust and tweak the mask later if necessary. Very often, it is efficient and more creative way of the image manipulation services.
