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;

/***比较两张图片的相似度*@authorGuihua**/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;

/**

* 比较两张图片的相似度

* @author Guihua

*

*/

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

try {

String[] value1 = list1[i][j].toString().split(",");

String[] value2 = list2[i][j].toString().split(",");

int k = 0;

for (int n=0; n

if (Math.abs(Integer.parseInt(value1[k]) - Integer.parseInt(value2[k])) < 5) {

xiangsi++;

} else {

busi++;

}

}

} catch (RuntimeException e) {

continue;

}

j++;

}

i++;

}

list1 = getPX(images[1]);

list2 = getPX(images[0]);

i = 0;

j = 0;

for (String[] strings : list1) {

if ((i + 1) == list1.length) {

continue;

}

for (int m=0; m

try {

String[] value1 = list1[i][j].toString().split(",");

String[] value2 = list2[i][j].toString().split(",");

int k = 0;

for (int n=0; n

if (Math.abs(Integer.parseInt(value1[k]) - Integer.parseInt(value2[k])) < 5) {

xiangsi++;

} else {

busi++;

}

}

} catch (RuntimeException e) {

continue;

}

j++;

}

i++;

}

String baifen = "";

try {

baifen = ((Double.parseDouble(xiangsi + "") / Double.parseDouble((busi + xiangsi) + "")) + "");

baifen = baifen.substring(baifen.indexOf(".") + 1, baifen.indexOf(".") + 3);

} catch (Exception e) {

baifen = "0";

}

if (baifen.length() <= 0) {

baifen = "0";

}

if(busi == 0){

baifen="100";

}

System.out.println("相似像素数量：" + xiangsi + " 不相似像素数量：" + busi + " 相似率：" + Integer.parseInt(baifen) + "%");

}

public static void main(String[] args){

BMPLoader.compareImage("E:\\12.bmp", "E:\\1.bmp");

}

}
