# PHP-OPENCV - PHP extension for Opencv
[](https://travis-ci.org/hihozhou/php-opencv) [](https://php.net/)
> **⚠️⚠️ NO LONGER IN ACTIVE DEVELOPMENT | 项目不再维护 ⚠️⚠️**
>Due to personal scheduling reasons, the project has been suspended for maintenance and it is hoped that the project code will provide useful value.
## Document
- [PHP OpenCV Document](https://doc.phpopencv.org)
## Requirements
- OpenCV 4.0.0+
- PHP7.0+
## Installation
### Use OpenCV docker(commendatory)
If you don't know how to install OpenCV, you can use my OpenCV docker image(only 300M, including opencv_contrib).
```bash
docker pull hihozhou/php-opencv
```
### Compile and install php-opencv extension
```bash
git clone https://github.com/hihozhou/php-opencv.git
cd php-opencv
phpize
./configure --with-php-config=your php-config path
make
make install
```
## Configure
php.ini
```
extension="your opencv.so path"
```
## Example
### LBPH face recognition
```php
use CV\Face\LBPHFaceRecognizer;
//use ...;
$src = imread('facePic.jpg');
$gray = cvtColor($src, COLOR_BGR2GRAY);
equalizeHist($gray, $gray);
$faceRecognizer = LBPHFaceRecognizer::create();
/* ... */ //get $images and $labels for train
$faceRecognizer->train($images, $labels);//How to get $image and $labels, see the document
/* ... */ //Face detection using CascadeClassifier
$faceLabel = $faceRecognizer->predict($gray);
/* ... */ //draw face and name
```
result:
### Image Processing
```php
//Obama.php
use function CV\{ imread, imshow, waitkey, namedWindow};
$im = imread('Obama.png');//load image
namedWindow('This is Obama id card',WINDOW_FULLSCREEN);//create window
imshow('This is Obama id card',$im);//show image on window
waitkey(0);
```
result:
Load image by gray
```php
$gray = imread('Obama.png',IMREAD_GRAYSCALE);
//or
use function CV\{ cvtColor};
$gray = cvtColor($im, COLOR_BGR2GRAY);
```
You can draw something.
e.g:
```php
use CV\{Mat,Scalar, Point, Size};
use function CV\{ellipse, imwrite, waitKey};
use const CV\{CV_8UC3};
$windowWidth = 600;
$thickness = 2;
$lineType = 8;
$matScalar = new Scalar(0,0,0);
$mat = new Mat($windowWidth, $windowWidth, CV_8UC3, $matScalar);
$point=new Point($windowWidth/2, $windowWidth/2);
$size=new Size($windowWidth/4, $windowWidth/16);
$scalar=new Scalar(255, 129, 0);
for($i = 0; $i <= 360; $i += 45){
ellipse($mat,$point,$size,$i,0,360,$scalar,$thickness,$lineType);
}
imwrite('./tests/ellipse.png',$mat);
```
result:
