Hi there,
I'm trying to recognize a dial symbol as a special character so I can locate it when I use the ocr function.
However, is not recognizing that symbol at all.
This is my image after training the model. I wanted to locate the green symbol.
Is there another way to do this?
Do you have any suggestion @Image Analyst?
Best

Hi Pedro,
I think you need to train an ocr to compensate for the symbol. you can refer to ocrTrain App in MATLAB. you manually have to collect enough data and train a classifier. After training you can export the file and use it in typical ocr workflow.
I hope this helps.
Cheers.
