How can I find where a specific string is on an image?

I was wondering if anyone knew of a w开发者_开发问答ay that I could feed an image file to a Python, C or Java program and get back the coordinates of where a specific string appears on the image?

What you're talking about is called Optical Character Recognition, or OCR.

OCR isn't easy to implement from scratch, but there are libraries out there. OpenCV can be used for OCR.

I looked into this a bit more. It turns out that sikuli does exactly what I needed.
