How to Use OCR Verify text

[pravin]

Hi all,

i want to use OCR verify text in my project, is anybody use

this VI for correct character reading in image so please reply.

If I remember correctly, someone used it to read the names of case structure cases a while back. I'll see if I can find the thread I'm thinking of.

It was actually an event structure. Here's the thread. Apparently it implements its own OCR, my mistake.

Here's one that I wrote with a different approach. What about the project are you trying to read? What have you tried so far?

Dear all,

my question is how to integrate NI Vision Function palate OCR- OCR Verify Text for correct character reading. not

relevant to above reply, is anybody integrate this utility in OCR/OCV.

You can start from the examples that ship with VDM (Vision Development Module, that you have I assume).

The example are fairly basic but they show how to use the different functions from the palette (character sets and all that stuff).

One of the big challenges in real world OCR applications is often to find a reference in the image to place the ROI, do you already have image samples in which you will have to find and read text?

Hope this helps
