JAVA使用Marvin在图片中搜索图片

marvin

Marvin是一个Java开源图像处理框架
项目地址

使用非常简单，按照tutorials一步一步就知道怎么部署代码。

依赖只需要添加marvin/framework/marvin_1.5.5.jar到classpath。

例子：

import marvin.image.MarvinImage;
import marvin.image.MarvinSegment;
import marvin.io.MarvinImageIO;

import java.awt.*;
import java.io.File;

import static marvin.MarvinPluginCollection.*;

public class Subimage {
    public Subimage(){
        MarvinImage window = MarvinImageIO.loadImage("E:\msC_desktop\batlogo.jpg");
        MarvinImage eclipse = MarvinImageIO.loadImage("E:\msC_desktop\wxlogo.jpg");

        MarvinSegment seg1;

        int startx = 500, starty = 0;
        seg1 = findSubimage(eclipse, window, startx, starty, 0.75);
        if(seg1 != null){
            System.out.println("Found:" + seg1.x1 + " " + seg1.y1 + " "+ (seg1.x2-seg1.x1) + " height:"+(seg1.y2-seg1.y1) );
            drawRect(window, seg1.x1, seg1.y1, seg1.x2-seg1.x1, seg1.y2-seg1.y1);
            MarvinImageIO.saveImage(window, "E:\msC_desktop\window_out.png");
        }else{
            System.out.println("NOT FOUND");
        }

    }
    private void drawRect(MarvinImage image, int x, int y, int width, int height){
        x-=4; y-=4; width+=8; height+=8;
        image.drawRect(x, y, width, height, Color.red);
    }
    public static void main(String[] args) {
        new Subimage();
    }
} 

效果如下：
