I’m trying to write some code to detect the numbers on Bibs for races.
I’ve been working with MBS’ OCR plugin but it’s not going as well as I need.
I think the problem is that they are very complicated scenes and not just paper through a scanner.
When complete I’m going to want to automate it so I’ll have to add a pattern recognition, eg discard “Chicago”, “Exit”, but keep “26016”. The discard/keep is easy enough, but maybe gives you a sense of complexity of the images.
Has anyone else tried something like this?
Any tips or hints would be greatly appreciated.
may be you should try with opencv ?
Did you try to set the white list of characters to recognize?
@Christian Schmitz , I did.
Oh, if you contact Jim Meyer he did a wonderful presentation at XDC this year about using Machine Learning from AWS and Google to detect things on an image. I would think this would be a wonderful use of such a technology.
@Christian Schmitz I’m reading online that this engine’s whitelist isn’t working correctly with some versions. I don’t know which your plugin uses.
@Bob Keeney, thanks for the suggestion. I don’t know Jim. Is he in this forum?
He’s a lurker and I don’t think he posts a lot.
OK, complete failure with MBS OCR (could be my fault), and I can’t get the OpenCV example to compile.
There are commercial products but they require uploading everything through a web server, and with the quantity and size of the images I’ll be dealing with, it’s just not an option.
I’m considering hiring a squad of high school kids to simply type them in!
That’s the cheaper option, no doubt.
