The basic implementation of global threshold processing for edge improvement is:
1. Calculate its boundary first, use Laplace or gradient transform to all.
2. Calculate the absolute value of the changed boundary image
3. Specify a threshold
This is a very basic thing, but the importance of the foundation is self-evident, I am sure I have known this knowledge, but now, I am not sure, this shows the importance of the record, the world there is no shortcut to find the right direction, and

In a programming language, there is a way to tell the compiler that a piece of data is immutable. There are two requirements
1. A compiler constant that never changes
2. A value that is initialized at run time, and this value is not changed
