I'm using the latest version of tesseract: 3.02. I successfully OCRed with vietocr gui. If I set it as screenshot mode, apply a smooth filter, and use the textbox to select each line one by one, I get a 100% correct OCR.
Now I am wondering, how can I automate this process? I want to be able to create a program or execute a command so that I give it the image and it does the above things automatically and outputs the OCR and the location of the OCRed text in the image file.
