Augmenting OCR and NLP

Image resolution needed for OCR return is a tricky subject. The general rule is a preferred resolution of 300 dpi (dots per inch). However, this generally applies to images of text obtained from a scanner and dpi values can be misleading when a camera is used to image the text. DPI is only relevant if the document size is 1:1 and focal distance will vary according to camera placement. Typically, one inch within the image obtained from a camera is not proportional to one inch within the text document.
