Can Microfiche Images Be OCRd?
Often we are asked by clients if it is possible to OCR microfiche images. It is believed in a lot of cases that due to the shrinking and reproduction of the images that the images cannot then have the text extracted enabling them to be edited and copied from.
So is it possible to OCR microfiche images?
Like any other type of document, once the
image is extracted it can be OCRd
The short answer is yes, microfiche images can be OCRd. The longer answer is that it can depend on the quality of the original documents which have been filmed on to the microfiche, the quality of the filming itself and the condition of the microfiche which can depend on if they have been correctly stored and looked after. Once any microfiche scanning company has scanned and extracted the images at their original size and resolution, it's all down to the quality of that image to define whether OCR can be completed successfully.
Even with poorly filmed images some OCR might be possible but may not be highly accurate. The best way to put it is that it is possible to OCR your microfiche images but the quality can differ depending on how it was originally filmed, the condition of the original documents and the condition of the film itself.
How do I test the OCR capabilities of my microfiche images?
The best way to test the water is to send a few examples off to a microfiche scanning company who's willing to offer a free sample and who will offer advice on the quality of the output which you'll also be able to see yourself.
