imshow('This is Obama id card',$im);//show image on window

Load image by gray
$gray = imread('Obama.png',IMREAD_GRAYSCALE);
//or
use function CV\{ cvtColor};
$gray = cvtColor($im, COLOR_BGR2GRAY);You can draw something.
e.g:
use CV\{Mat,Scalar, Point, Size};
use function CV\{ellipse, imwrite, waitKey};
use const CV\{CV_8UC3};
$windowWidth = 600;
$thickness = 2;
$lineType = 8;

$point=new Point($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);
