Using C#, I'm trying to detect whether a document (Invoice to be more specific) is handwritten or printed.
Edited: I don't have to convert handwritting to actual words. Just have to know that handwritting is existing in the scanned document.
Tried OCR method by checking the percentage of meaningless character exceed certain threshold but often gave wrong result due unexpected behavior such as a line drawn across the printed words which cause OCR to capture wrong result.
Any other recommendation on how can I detect a document is handwritten or printed?
Not really specific to c# only as what I'm looking for is a tool to help in identifying handwritting existence in a scanned document. C# is what I'm using primarily now thus mentioned it.
