higher than the two sides. This is also a kind of typical diagram, called pulse (Impulse). It can be seen that median filtering is very effective for impulse noise. Combined with the above three class diagram, it is not difficult to draw the following conclusions: Median filtering is easy to remove outliers, line noise while maintaining the edge of the image, it can be very good to remove the binary noise, but the Gaussian noise is powerless. It is important to

Behavioral parameterization, a software development model that handles frequently changing requirements. Principle: After writing similar code, try to abstract it.Method 1: Add parameters to the method.Method 2: Define a family of algorithms, encapsulate them (called "policies"), and then select an algorithm at run time.Behavioral parameterization: Allow methods to accept multiple behaviors (or strategies) as parameters and use them internally to accomplish different behaviors.Strategy Patternis

inverted, that is, the large number in front. Just like the "Mo" character Unicode code 0X83AB, press big endian to become 0xab83.BOM (Byte Order Mark):Because of the problem of byte order in Unicode storage, inserting a non-existent character (ZERO WIDTH no-break SPACE) in front of the Unicode text is used as a flag to distinguish between the two kinds of byte-order.
