Real-time Image Recognition app using WCF and Silverlight

Is it possible (if so, effective) to do a Real-time Image Recognition app using WCF and Silverlight?. This app is supposed to be implemented on Windows Phone 7 platform. As the pro开发者_运维技巧cessing can't be done inside WP7 itself I'm hoping to stream-out the video feed using web services...

Correct me if I'm having any mis-understanding...

Thanks.

Have a look at http://visualfindr.codeplex.com/

It is a WP7 wrapper to an image recognition service. It requires an image to be selected/passed or photo to be taken to work with as third party access to the camera stream is not currently available on Window Phone 7.

Not currently possible sorry, you can't access the camera directly. You can only start a new "task" to capture an image or video - The OS takes over for the duration of the task and will return the result to your application.

So yes you can do image capture/recognition (As you've already stated it would be highly recommended to offload this to a server) but no it can't be done in real time.
