OpenCV和PHP的人脸识别技术

OpenCV安装之前必须依赖的包：（请先安装好）
pkgconfig
libpng
zlib
libjpeg
libtiff
python

[OpenCV安装] www.opencv.org.
tar xvzf OpenCV-1.0.0.tar.gz
cd opencv-1.0.0
./configure
make
make install
make check (检查是否安装全部正确)

[facedetect] http://www.xarg.org/download/facedetect-1.0.0.tar.gz
tar xzvf facedetect-1.0.0.tar.gz
cd facedetect-1.0.0
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make test
make install

[ImageMagick] http://www.imagemagick.org/
tar jxvf ImageMagick-6.5.0-0.tar.bz2
cd ImageMagick-6.5.0-0
./configure
make
make install

[imagick] http://pecl.php.net/imagick
tar zxvf imagick-2.3.0b1.tgz
imagick-2.3.0b1
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make test
make install


[配置]
ll /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
看看有没有 facedetect.so 和 imagick.so
vi /usr/local/php/lib/php.ini
在[PHP]模块下增加：
extension = facedetect.so
extension = imagick.so
重启apache


[测试代码]


从openCV源代码/data/haarcascades/里头取出所有xml文件放在php的执行目录下





//------------------


// 监测有几个人脸


//------------------


//检查有多少个脸型


var_dump(face_count('party.jpeg', haarcascade_frontalface_alt.xml'));


//返回脸型在图片中的位置参数，多个则返回数组


$arr = face_detect('party.jpeg', haarcascade_frontalface_alt2.xml');


print_r($arr);





//------------------


// 人脸扭曲


//------------------


setFillAlpha(0.0);


//$draw->setStrokeColor ($borderColor);


//$draw->setStrokeWidth (1);


if(is_array($all)){


foreach ($all as $v){


    $im_cl = $im->clone();


    $im_cl->cropImage($v['w'],$v['h'],$v['x'],$v['y']);


    


    $im_cl->swirlImage(60);


    $im->compositeImage( $im_cl, Imagick::COMPOSITE_OVER , $v['x'], $v['y'] );


    


    //$draw->rectangle($v['x'],$v['y'],$v['x']+$v['w'],$v['y']+$v['h']);


    //$im->drawimage($draw);


    


    


}


}


header( "Content-Type: image/png" );


echo $im;


}else{


?>

} ?> //------------------ // 人脸识别 //------------------ 人脸识别

PS: 请上传一张带有人脸的图片
$v){ $tmp_name_new = $tmp_name."_".$k; $x = $v['x']; $y = $v['y']; $w = $v['w']; $h = $v['h']; $dst_pic = "./".$tmp_name_new.$fix_pic; // echo $src_pic."
