How fast is OCR Software? OCR Performance Testing

OCR Performance Testing

So which Desktop Optical Character Recognition Software is the fastest? Has the best overall performance when converting images to Word? When converting images to PDF?

I ran some testing with 4 basic desktop OCR applications to see which would have the fastest conversion times. The OCR applications are:

-eCopy Desktop (Uses the ReadIRIS OCR Engine)

-Adobe 8

-Paperport 11

-OmniPage 15

I ran all the tests on a 9 month old laptop, with a Dual Core 2 GHz processor, and 2 GB of memory. I utilized all the "out of the box" settings on the apps, with no performance tuning of settings, and I timed the speed of the applications to convert a 100 page TIFF image to Word and to Adobe Image and Text PDF.

Results of the OCR Speed Test in minutes and seconds(Word/PDF):

eCopy Desktop 4:25/2:58

Adobe 8 3:54/3:22

OmniPage 15 2:16/2:16*

PaperPort 11 2:35**

*With OmniPage you run the conversion process and then save to your preferred format.

**PaperPort just had text conversion capabilities.

I have to note that the eCopy Desktop test can be misleading in that it performs auto-orientation on all the pages before performing OCR. Also note that when evaluating an OCR application, speed is not the only factor. You need to decide up front whether you want speed, accuracy, both, or want to focus on formatting. I will write another article on formatting and which application is best in the near future.
