Recently, I was wondering how to convert a color image into a grayscale image, view the information, and finally achieve the expected effect. Now I am posting the code to share with you: Public Bitmap ConvertGrayImg (Bitmap img1){Int width = img1.getWidth ();Int height = img1.getHeight ();Int [] pix = new int [width * height];Img1.getPixels (pix, 0, width, 0, 0, width, height); // The third parameter, width

multiple IP packets, which are called IP segments. This segmentation method can improve the efficiency of Dos attacks. If the firewall can prevent segment data packets from passing through the firewall, it can effectively prevent Dos attacks. On the PIX Firewall, you can use the Fragment command to prevent multipart packets from passing through the firewall. Run the following command: fragment chain 1 outside. What does this command mean? Parameter 1

(less than CMake 3.0 cannot be built). The second sentence means building a solution named Tesseract-api-examples. The third sentence indicates the addition of subdirectories Basic-example . The meaning of adding subdirectories is actually starting to execute CMakeLists.txt in subdirectories. So, if you want to add_subdirectory add subdirectories, you have to make sure that the CMakeLists.txt file is in this subdirectory.Now, let's go into the Basic-example folder and create a new two files: Ba

The mean blur principle is very easy and I will not explain it. After I tested it, the compilation code processing time is about 1-2 ms. The processing time of CPP Code is about 3-4 ms. Only key code is provided here, and other code can be found here.
