JAVA比较两张图片相似度的方法

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;

/***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

*/

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];

}

}
