OCR thershould with webcam USB

Hello everyone. I tell them I am trying to apply OCR to capture an image of a webcam. The problem is that I can not process the image with thershould (go to black and white).
The webcam image (RGB) I apply THERSHOULD with VDM parameters that allowed me to highlight text (white and black).
Could you give an example of how to properly use a webcam image for processing.
What I do is capture the image, burn it (it could be processed without prior record?). This recorded image is processed (thershould) but the process seems never become complete.
Once more thank you very much.

The images you will be getting from webcam will most likely be a RGB image(color). Use color plane extraction and convert it into a greyscale image and then you will be able to use ocr as well as apply threhold. You can also direclty threshold the image using color thresholding.

Hi!

I'm interested in such an application too. Have you succeeded in OCRing the webcam output?
