catalogue Otsu threshold Algorithm flow Flow chart representation result code Otsu threshold Otsu threshold, also known as the maximum variance threshold, was proposed by Otsu zhanzhi of Japan in 1979. It is derived based on the principle of discrimination and least square method. Its basic idea is to maximize the variance between cla ...

summary Violent recursion is an attempt (local attempt)The problem is transformed into a sub problem of the same kind of problem with reduced scaleSpecify the condition for the end of recursion (base case)After getting the results of the subproblem, there is a decision-making processDo not record the solution of each sub problem, try the m ...

1. Find the first character in the string that appears only once: The first character that appears only once_ Niuke Tiba_ Niuke (nowcoder.com) Since the characters in the computer are ultimately represented by the asker code, you can create an array, and the number of times each character appears will be placed in the subscript position corres ...

Model testing system is a sub project of ZStack woodpecker. Through the finite state machine and behavior selection strategy, it can generate random API operations and run until a defect or predefined exit condition is encountered. ZStack relies on model testing to test boundary use cases that are difficult to meet in the real world, and comple ...

In Java, there are many scenarios for generating random numbers, so in this article, we will take an inventory of the four ways to generate random numbers, the differences between them and the corresponding scenarios of each way. 1.Random Random class was born in JDK 1.0. The random number it generates is pseudo-random number, that is, regula ...
