Face detection in PHP

Question

Does anybody know of a good way to do face detection in PHP? I came across some code here that claims to do this, but I can\'t seem to get it to work properly. I\'d like to

The project has been upgraded on github repository by following this link Face detection

The problem was on the loop, this code works fine :

for ($i=1; $i<$ii_h-1; $i++) {
        $ii[$i*$ii_w] = 0;
        $ii2[$i*$ii_w] = 0;
        $rowsum = 0;
        $rowsum2 = 0;
        for ($j=1; $j<$ii_w-1; $j++) {
            $rgb = ImageColorAt($canvas, $j, $i);
            $red = ($rgb >> 16) & 0xFF;
            $green = ($rgb >> 8) & 0xFF;
            $blue = $rgb & 0xFF;
            $grey = (0.2989*$red + 0.587*$green + 0.114*$blue)>>0;  // this is what matlab uses
            $rowsum += $grey;
            $rowsum2 += $grey*$grey;

            $ii_above = ($i-1)*$ii_w + $j;
            $ii_this = $i*$ii_w + $j;

            $ii[$ii_this] = $ii[$ii_above] + $rowsum;
            $ii2[$ii_this] = $ii2[$ii_above] + $rowsum2;
        }
    }

Good luck
