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
