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 + " width:"+ (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：
