Hello
My name is Emanuel Indermühle and i would like to use ocropus to test
the document analysis algoritms on handwritten documents.
I installed the latest svn version of iulib and ocropus on ubuntu 8.04
and wrote a small lua script to test the segmentation functionality
-----------------
require 'lib.util'
require 'lib.path'
require 'lib.headings'
require 'lib.hocr'
require 'lib.paragraphs'
require 'lib.xml'
require 'lib.align'
image = util.read_image_gray_checked(arg[1])
segmenter = make_SegmentPageByRAST()
seg = intarray()
segmenter:segment(seg, image)
check_page_segmentation(seg)
write_png_rgb("result.png",seg)
dshow(seg,"huhu")
----------------------------------
the last two lines did not work for me:
- write_png_rgb or write_png seam not to exists, or i can at least not
find in what file it is defined.
the following error is printed:
ocroscript: pageSegmentation.lua:14: attempt to call global
'write_png_rgb' (a nil value)
- dshow raises no error, but nothing happens.
Can you please tell me, how i can view the segmentation in any form?
Thanks a lot,
Emanuel
