Java comparison method of two picture similarity _java

This article illustrates a Java comparison of two picture similarity methods. Share to everyone for your reference. Specifically as follows:

Summary:

Importjava.awt.image.BufferedImage;
Importjava.io.File;
Importjavax.imageio.ImageIO;
/*** Compare the similarity of two pictures * @authorGuihua **/publicclassbmploader{//changed into binary code
PUBLICSTATICSTRING[][]GETPX (Stringargs) {int[]rgb=newint[3];
Filefile=newfile (args);
Bufferedimagebi=null;
Try

The main code is as follows:

Import Java.awt.image.BufferedImage;
