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

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

<?php

if($_FILES){

$img = $_FILES['pic']['tmp_name'];

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

//$arr1 = face_detect($img, 'haarcascade_frontalface_alt_tree.xml');

if(is_array($arr1)) $all =array_merge($arr,$arr1);

else $all = $arr;

$im = new Imagick($img);

//$draw =new ImagickDraw();

//$borderColor = new ImagickPixel('red');

//$draw->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;

if($allowtype == 0) {

}

$tmp_name = time();

$src_pic = "./".$tmp_name.$fix_pic;

move_uploaded_file($_FILES['pic']['tmp_name'], $src_pic);

echo `$cmd`;

$pic_src[] = "./".$tmp_name.$fix_pic;

$pic_dst[] = "./".$tmp_name_new.$fix_pic;

}

}

foreach($pic_src as $key => $value) {

echo "<img src='".$value."'> => <img src='".$pic_dst[$key]."'><br>";

}

}

?>

　　目前，还为测试，等应用后，再公布实验结果～～
