JAVA比较两张图片相似度的方法

本文实例讲述了JAVA比较两张图片相似度的方法。分享给大家供大家参考。具体如下：

摘要：

importjava.awt.image.BufferedImage;
importjava.io.File;
importjavax.imageio.ImageIO;
publicclassBMPLoader{//改变成二进制码
publicstaticString[][]getPX(Stringargs){int[]rgb=newint[3];
Filefile=newFile(args);
BufferedImagebi=null;
try

主要代码如下：

import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;

public class BMPLoader {
  // 改变成二进制码
  public static String[][] getPX(String args) {
    int[] rgb = new int[3];
    File file = new File(args);
    BufferedImage bi = null;
    try {
      bi = ImageIO.read(file);
    } catch (Exception e) {
      e.printStackTrace();
    }
    int width = bi.getWidth();
    int height = bi.getHeight();
    int minx = bi.getMinX();
    int miny = bi.getMinY();
    String[][] list = new String[width][height];
    for (int i = minx; i < width; i++) {
      for (int j = miny; j < height; j++) {
 int pixel = bi.getRGB(i, j);
 rgb[0] = (pixel & 0xff0000) >> 16;
 rgb[1] = (pixel & 0xff00) >> 8;
 rgb[2] = (pixel & 0xff);
 list[i][j] = rgb[0] + "," + rgb[1] + "," + rgb[2];
      }
    }
    return list;
  }
  public static void compareImage(String imgPath1, String imgPath2){
    String[] images = {imgPath1, imgPath2};
    if (images.length == 0) {
      System.out.println("Usage >java BMPLoader ImageFile.bmp");
      System.exit(0);
    }
    // 分析图片相似度 begin
    String[][] list1 = getPX(images[0]);
    String[][] list2 = getPX(images[1]);
    int xiangsi = 0;
    int busi = 0;
    int i = 0, j = 0;
    for (String[] strings : list1) {
      if ((i + 1) == list1.length) {
 continue;
      }
      for (int m=0; m
