Is possible to do OCR recognition from a bitmap?

Hi all,
Is possible to develop a program in CVI to make OCR recognition from a scanner or from a bitmap?
Many thanks,
P.D.any introduction into the OCR world will be welcome!!

Hi Xavi,

You would need IMAQ Vision and NI OCR for LabWindows/CVI.

IMAQ Vision for LabWindows/CVI adds multipurpose image processing and machine vision capabilities to LabWindows/CVI and C programming environments.

NI OCR for LabWindows/CVI provides functions to perform Optical Character Recognition (OCR) directly from an IMAQ Vision Image.

Basically what you do is train the characters you want to recognize using the NI OCR Training Interface and save this info into a character set file ("*.abc").
From LabWindows/CVI you open the image containing the characters to recognize, set the appropiate Region Of Interest (ROI) that contains your string and recognize the characters making use of your previously generated character set file and several OCR options gr
ouped into read (read strategy, acceptance level...) processing (threshold mode, threshold values,...) and spacing (min char spacing, min/max char size,...) options.

Hope this helps.
