Using tesseract to recognize license plates

Question

I\'m developing an app which can recognize license plates (ANPR). The first step is to extract the licenses plates from the image. I am using OpenCV to detect the plates bas

Answer 1

Here is my real world example with trying out OCR from my old power meter. I would like to use your OpenCV code so that OpenCV does automatic cropping of image, and I'll do image cleaning scripts.

• First image is original image (croped power meter numbers)
• Second image is slightly cleaned up image in GIMP, around 50% OCR accuracy in tesseract
• Third image is completely cleaned image - 100% OCR recognized without any training!
