用OpenCV开发人脸识别软件，用Java好还是用C/C++好

我去年就用opencv开发的android手机端的关于人脸识别的增强现实应用。我可以很明确的告诉你，java的opencv顶多调用摄像头用，图像处理都用c++的opencv。对于opencv的开发，不管从开发效率还是执行效率，绝对是c++。java版的opencv想都不要想。

如何开发Java动态人脸识别

1.环境搭建

整个项目的结构图

2.编写DetectFaceDemo.java,代码如下：

[java] view plaincopy

package com.njupt.zhb.test;

import org.opencv.core.Core;

import org.opencv.core.Mat;

import org.opencv.core.MatOfRect;

import org.opencv.core.Point;

import org.opencv.core.Rect;

import org.opencv.core.Scalar;

import org.opencv.highgui.Highgui;

import org.opencv.objdetect.CascadeClassifier;

//

// Detects faces in an image, draws boxes around them, and writes the results

// to “faceDetection.png”.

//

public class DetectFaceDemo {

public void run() {

System.out.println(“\nRunning DetectFaceDemo”);

System.out.println(getClass().getResource(“lbpcascade_frontalface.xml”).getPath());

// Create a face detector from the cascade file in the resources

// directory.

//CascadeClassifier faceDetector = new CascadeClassifier(getClass().getResource(“lbpcascade_frontalface.xml”).getPath());

//Mat image = Highgui.imread(getClass().getResource(“lena.png”).getPath());

//注意：源程序的路径会多打印一个‘/’，因此总是出现如下错误

/*

* Detected 0 faces Writing faceDetection.png libpng warning: Image

* width is zero in IHDR libpng warning: Image height is zero in IHDR

* libpng error: Invalid IHDR data

*/

//因此，我们将第一个字符去掉

String xmlfilePath=getClass().getResource(“lbpcascade_frontalface.xml”).getPath().substring(1);

CascadeClassifier faceDetector = new CascadeClassifier(xmlfilePath);

Mat image = Highgui.imread(getClass().getResource(“we.jpg”).getPath().substring(1));

// Detect faces in the image.

// MatOfRect is a special container class for Rect.

MatOfRect faceDetections = new MatOfRect();

faceDetector.detectMultiScale(image, faceDetections);

System.out.println(String.format(“Detected %s faces”, faceDetections.toArray().length));

// Draw a bounding box around each face.

for (Rect rect : faceDetections.toArray()) {

Core.rectangle(image, new Point(rect.x, rect.y), new Point(rect.x + rect.width, rect.y + rect.height), new Scalar(0, 255, 0));

}

// Save the visualized detection.

String filename = “faceDetection.png”;

System.out.println(String.format(“Writing %s”, filename));

Highgui.imwrite(filename, image);

}

}

3.编写测试类：

[java] view plaincopy

package com.njupt.zhb.test;

public class TestMain {

public static void main(String[] args) {

System.out.println(“Hello, OpenCV”);

// Load the native library.

System.loadLibrary(“opencv_java246”);

new DetectFaceDemo().run();

}

}

//运行结果:

//Hello, OpenCV

//

//Running DetectFaceDemo

///E:/eclipse_Jee/workspace/JavaOpenCV246/bin/com/njupt/zhb/test/lbpcascade_frontalface.xml

//Detected 8 faces

//Writing faceDetection.png

人脸识别系统使用java的开发

现在主流的还是用的百度，千搜等公司的在线API，就是传图片过去，等接收结果就行，seetaface这个东西太复杂了。

java 人脸识别sdk推荐个好用的？

推荐虹软的，他们的是免费下载的，支持Java，也支持多种平台的开发，接入也比较简单，重点是功能还比较强大。

java怎么实现人脸识别？

应该可以通过java调用别人的人脸识别的接口,主要是利用图像处理的技术,识别关键点
