No prob. OmniPage is looking to be the frontrunner at the moment balanced upon accuracy vs. speed. These things do cost though... Tesseract doesn't do too badly but absolutely requires the image cleanup stuff we did for MBagger. The others also tend to do better with our preprocessing.

Do you mind keeping me informed about the results you reach?

So, using a handheld scanner (like MBagger) it gets a scan of the address label, OCRs it and extracts relevant information that can be passed on to their existing (VB) application, along with, say weight from electronic scales etc. Currently we are trialling various 3rd party OCR engines: Abbyy, OmniPage and Tesseract (open source). Of course, I'm making it vastly configurable so there will many potential uses... Sorry if you were actually think that the OCR itself was done by us in Smalltalk ;-) Regards, Gary ----- Original Message ----- From: Lorenzo Schiavina To: [email protected] Sent: Thursday, August 04, 2011 8:19 AM Subject: Re: [Pharo-project] Polymorph improvements Hi Gary, I have seen from your screenshots that you are working on OCR projecr; can you give my some information about it?

I've added an issue with some tweaks/improvements to a few Polymorph classes. http://code.google.com/p/pharo/issues/detail?id=4590 Groupboxes can now have dynamic content (model/getContentSelector based). Abaility to create icon lists via builder/TEasilyThemed. Expander labels now LabelMorphs rather than TextMorphs (can therefore appear as disabled) IncrementalSliderMorphs now honour minWidth/minHeight in layouts Panel morphs allow event based mouse over handling (call to super was missing). Label groups allow for nil labels (equates to empty string) Regards, Gary
