I am trying to develop an application with PHP.

There are two possible ways this application will be developed. The first one is to try to do something like [www.picnik.com](http://www.picnik.com), image processing directly on the browser.
The other is to develop CBIR (content-bases image retrieval) algorithms.

So, is it possible to send an image from a PHP script to an OpenCV program? Or even display the image being manipulated in real time?

Thanks.
