Image processing in ARM (angstrom)

Question

I'm new to ARM and linux in general but I have eclipse set up for programming my beaglebone black (running angstrom). I want to process an image (local file) and then use the processed image information to turn on/off some LEDs.

What's the most best/most efficient way to process images with my setup? Should I make some script to process the image in Matlab or linux equivalent? If so how would I get the information from those programs into my c++ program? Or should I simply process the image in c++ (probably more difficult)?

Answer 1

This highly depends on what do you mean by process. If you want to do something complicated, I would recommend OpenCV since it offers a vast range of functionalities you can use to process your images.

That being said, if by process you mean extract text from images, you could take a look at Tesseract which is an open source OCR. If you will be going for an OCR, you could use OpenCV to do some pre-processing to make the text extraction process easier and more succesful.

If I am understanding you correctly, then you could take a look at this tutorial which should do what you are after (you start with an image and end up with a pixellated version of it).
