Understanding: 1.watershed () function accepts two parameters, void watershed (Inputarray image, Inputoutputarraymarkers) The input image is 8-bit 3-channel, markers with a tagged image (or map), and the result is saved in markers. 2.markers sets the pixel to 1,2,3 according to the Mark .... The 3.findContours contours parameter is a detected contour array, count records the Contour group number, and the markers result is 1,2,.... count, so the color is also randomly set to count. 4. According

In the process of managing a server, often when editing this file, suddenly to see other information, this is the time, the usual way is to exit the edit, and then to view the information. But if we combine FG with BG command, we can make our work more efficient. The commands involved in inter-process switching are as follows: CTRL + CTerminate and exit the execution of the foreground command and return to the shellCtrl+zPause the execution of the

Displaying a large amount of data on a page is a common practice in Web projects, but limited to the size of the screen, we usually need to display the data paging to make it easier for users to read, so paging is an essential part of the project. PEAR::P Ager is a powerful paging class that is very handy to use. System requirements: php4.3.*/php5,pear::P ager PEAR::P Ager has two pagination display modes, one is jumping, the other is sliding. What is the difference between the two, let's look a
