> Tesseract OCR parser works well with images containing English text. However, there is
possibility of improvement in case of alphanumeric and numeric content which require training
Tesseract with the relevant cases in order to better extract content from images. Such a customization
can be helpful in extraction of serial numbers from images of counterfeit electronics and
other applications focussing on atypical textual content.
