Find a character, in particular a number, in a photograph - is there any frame?

Question

I'm currently looking for a suitable way to find prices on an image. Images are painted and captured using a camera or smartphone. I have already done some processing, for example, color threshold, morph. reconstruction and other steps to place and trim the region in which prices are located. Now I want to get price recognition.

In our project, we already tried some OCR frameworks (more precisely, Tesseract with Tessjeract, as well as JOCR), but the recognition of numbers in photos is very poor. We also conducted some experiments with pre-processed images (color threshold value, opening, segmentation, etc.). But with the tested framework, no satisfactory results were achieved.

We also thought that neural networks could be a good way, but all project members do not have enough knowledge about them, and there is a very short project time space. Now we are looking for an infrastructure that can find numbers in (pre-processed) images.

Can anyone suggest a framework that prefers a Java framework that could do this?

I would be glad if there were some suggestions.

Answer 1

I'm not sure if there is a framework that you guys need *.

But I did something almost the same (a mobile application with OCR functionality) with Neural Networks, and it gave relatively good results.
