I'm writing an application that will allow users to create custom printable surveys. Once the surveys are filled out we'll scan the images and then we want to programmatically process the results.
It doesn't seem like a really hard problem to solve because the image processing tasks are pretty easy but it also seems like something someone has already solved. Does anyone know of an available (ideally open source) solution for this problem?
There are a lot of software solutions that will do this for us but they seem really expensive compared to the functionality we want.
Our leading contender right now is just to implement the functionality through the Java Advanced Imaging API.
Also - the library doesn't have to be Java, but all things being equal (which they aren't) that would be our preferred solution.
