7 Segment Display OCR

FraggerFox — Thu, 05 Aug 2010 06:18:57 GMT

Hi all,

I have a 7 segment number image and I want to convert the image into text using OCR. I am already doing this with some other tool, but it is not able to properly do OCR for 7 segment display image. Can anyone suggest me a good OCR software which can read 7 segment display number which I can call through LabVIEW?

I don't have the Vision development module, so I can't use the IMAQ VIs.

Thanks.

Fragger Fox.

Have you used IMAQ OCR thing for this?

I don't have VDM.

OCR is an add-on package for IMAQ Vision

Do we need to have licensed Vison module for this?

If not, can you please tell me where can I get this addon for?
