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; Knowledge

First, design a class to handle the addition and subtraction of this behavior: Public class manythread { privateint j = 0; Public synchronized void Inc () { J++ ; + "Inc" + J); } Public synchronized void Dec () { J--; + "Dec" + j);} }And then make the call Public classMyTest {PrivateManythread Manythread =NewManythread (); Public Static voidMain (string[] args) {MyTest MyTest=NewMyTest (); Mytest.test (); } Public voidTest () { for(

Ask: Design 4 threads, where two threads add 1 to J each time, and two threads reduce the J each time by 1. Write out the program. Answer: The following procedure uses the internal class to implement the thread, to the J increases or decreases when does not consider the order question. public class threadtest1{Private int J. public static void Main (String ar
