Any chance we could get someone to re-upload that "ShowOCRunderMouse.zip" file?

Optical Character Recognition --- gocr 0.40
using: gocr [options] pnm_file_name # use - for stdin
options:
-h - get this help
-i name - input image file (pnm,pgm,pbm,ppm,pcx,...)
-i - - read PNM from stdin (djpeg -gray a.jpg | gocr -)
-o name - output file (redirection of stdout)
-e name - logging file (redirection of stderr)
-x name - progress output (file or fifo)
-p name - database path (including final slash, default is ./db/)
-f fmt - output format (ISO8859_1 TeX HTML XML UTF8 ASCII)
-l num - threshold grey level 0<160<=255 (0 = autodetect)
-d num - dust_size (remove smaller clusters, -1 = autodetect)
-s num - spacewidth/dots (0 = autodetect)
-v num - verbose [summed]
1 print more info
2 list shapes of boxes (see -c)
4 list pattern of boxes (see -c)
8 print pattern after recognition
16 print line infos
32 debug outXX.pgm
-c string - list of chars (_ = not recognized chars, debug)
-C string - char filter (ex. hexdigits: 0-9A-Fx, only ASCII)
-m num - operation modes, ~ = switch off
2 use database (early development)
4 layout analysis, zoning (development)
8 ~ compare non recognized chars
16 ~ divide overlapping chars
32 ~ context correction
64 char packing (development)
130 extend database, prompts user (128+2, early development)
256 switch off the OCR engine (makes sense together with -m 2)
-n 1 only numbers
examples:
gocr -v 33 text1.pbm # some infos + out30.bmp
gocr -v 7 -c _YV text1.pbm # list unknown, Y and V chars
djpeg -pnm -gray text.jpg | gocr - # use jpeg-file via pipe

The Tesseract OCR engine was one of the top 3 engines in the 1995 UNLV Accuracy test. Between 1995 and 2006 it had little work done on it, but it is probably one of the most accurate open source OCR engines available. The source code will read a binary, grey or color image and output text. A tiff reader is built in that will read uncompressed TIFF images, or libtiff can be added to read compressed images.

Here is another OCR demo script: ShowOCRUnderMouse.zip (contains all needed files). It does not 'optimize' the image before OCRing, but I found that this 'optimizing' (with potrace or netpbm) does not really generate much better results.



Enjoy!
