First, the principleThe bilateral filter (bilateral filter) is a filter that can be used to remove noise and edge. This effect can be achieved because the filter is composed of two functions: one function is determined by the distance between the

Recognize standard library Bitset typesA bit is a concise way of storing yes/no (1 or 0) information for a set of items or conditions, then the bit set is an ordered set of bits. The Bitset class provided by the standard library in C + + is very

C + + as a set of extensions of language, almost all C programs can be compiled and run in C + +, but note that C program may use keywords in C + + as variables, such as in C: int class = 0; But that doesn't work in C + +. For convenience, we can
