Well, the question is in the subject. Does any one know of a portable OCR program?

Old thread update:

Did some tests on the three that are on the site:

  1. PDF XChange Viewer with OCR plugin - Recommended. At least as good as many commercial tools I've used. Note that you'll have to convert images over to PDF, which can also be done with some portable tools: FastStone can batch convert and PDFTK Builder will combine many PDFs into one document (Docx2rtf would also probably work).

  2. IrfanView with OCR plugin - works pretty well, good for quickly pulling words from a screencap or other image.

  3. SoftiFree OCR - doesn't work if the document isn't very high quality.

Actually I did some tests with this and it doesn't have to be high quality, it just has to be big, I know, it's odd.

I made myself an Irfanview script to convert images, I found these were the best settings:
Code:
/resample /resize=(200p,200p) /resize=(200p,200p) /bpp=1
Yes, I double the size and then double it again. :) This works out better than just quadrupling it, then I convert to black and white.

Do any portable (automated) OCR programs support Chinese Language :?:

Retyping Chinese is problematic at best for a non speaker,
so using OCR and copy paste would be great.

I found a program COCR2 that could be portable (The website claims no registry modification) but ...

COCR2 is not automated as it lacks the ability to segment text into separate characters without user input.

Think this might do the trick.

The results were not as good as English OCR.

Also manually converting with COCR2 produced better results probably owing to manual segmentation of text.

Though it could just be the text I chose for the test.

PDF-XChange Viewer evidently supports Chinese: http://www.tracker-software.com/pdf-xchange-viewer-ocr
