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;

Modulo 2 is a binary algorithm, the core ofCRC calibration technology, so before we analyze the CRC algorithm, we must grasp the rules of modulo 2 operation. In the same way as arithmetic, modulo 2 also includes modulo 2 plus, modulo 2 minus, modulo

Today I learned the Example 2-2 of "Advanced Programming in UNIX environment", but I am very confused.
I created a directory named sample2_2, put the source code in it, compile it, and generate the sample2_2 file. Then copy pathconf. sym and sysconf. sym to this directory.
Run the following command:
./Sample2_2 pathconf. sym
The result is as follows:
No symbol for arg_max
Arg_max = 2621440

page's logic. The JSP is compiled into a servlet (the JSP compiles to a servlet), as we have defined clockservlet, which is equivalent to writing the HTML section and evaluating the Java section (that's equivalent to writing Out the HTML portions,and evaluating the Java portions). In a sense, JSPs is just another way to write the servlet code.JSPs is often criticized for being too powerful. Because the entire Java language can be obtained from a JSP, there is a risk that the business logic may
