Convert javascript to PHP

There is a face recognition script written in JavaScript: [login to view URL] The script consists of three parts, as you can see here: [login to view URL] - [login to view URL] (single variable with lots of data) - [login to view URL] (the actual face recognition) - [login to view URL] (jquery plugin integration) Your job will be to write a PHP script which implements the very face recognition functionality, based on the javascript algorithm. Write functions or a class in PHP which implements the following function: - as an input, it takes image file data string (PNG or JPG or whatever supported by PHP's GD), use imagecreatefromstring() function in php to autodetect the format - as output (return value), it returns array of coordinates (numbers) of square boxes for detected faces, if any. If there are any other supported functions by the javascript sources, we can ignore them. I need only as I mentioned a simple function which gets some photo and returns array of coordinates where the faces are. Note that the javascript code uses WEB WORKERS. We don't need paralelism in PHP so feel free to make it single-threaded. You should use PHP's native functions for images (GD). Your result will be single PHP file with the function(s) and the cascade variable. You must copy&paste there the entire string and use PHP's json_encode() function, I should be able to copy&paste the cascade variable myself when it updates in the original sources.
