Suppose rand5 can generate 1 ~ randomly ~ Use rand5 to generate rand7 () 1 ~ 7 (Equal Probability)
1. use rand5 to obtain rand2 (). When the number generated by rand5 is greater than 2, It loops until it generates 1 or 2 and the probability of generating 1 and 2 is
The Fibonacci Sequence, also known as the Golden series. In mathematics, the Fibonacci series are defined as follows by recursive Methods: F0 = 0, F1 = 1, Fn = F (n-1) + F (n-2) (n> = 2, in modern physics, quasi-crystal structure, chemistry, and other fields, the Fibonacci series are directly applied. Now, from an algorithm perspective, recursive and non-recursive methods are used for implementation:

PrefaceAlthough I have been developing C/C ++ for several years, I feel that my basic aspects are still a little weak. I am not clear about many details. I hope to write a blog to deepen my understanding.
I recently read this book and felt that I had benefited a lot. So I decided to write some articles to introduce my understanding of these articles.

At this time, there will be no master in this cluster, there are no master two slave instances to compete. After the competition, slave1 gave slave2, or slave2 gave slave1.

Opencv experiences (1)
The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image processing, such as contour processing;
