Detect an image from a Live Camera Feed - Iphone

I need a simple working application (with source code) that should be able to recognize a given image with the result of a Live Camera Feed from the Camera app of the Iphone and when recognised sends the user to a web URL. The application has to be able to: - Download a file from the server/URL (i.e. [login to view URL]) which contains the name of the .png image and the accompanied URL to link to. - Download the images from the [login to view URL] file and store them in a temp location and keep the data there until [login to view URL] changes. - There should be a proximity percentage setting in order to be able to set of how accurate the similarity should be. - When the app recognizes any of the images, it should redirect the user to the specified URL automatically. - The buyer owns the rights of the source code and the application.
