TODO LIST
|
||
|
|
|
||
|
|
Please send any ideas.
|
||
|
|
|
||
|
|
Next release (0.4x)
|
||
|
|
- quality test script for groups of samples (to ensure improvement in recognition)
|
||
|
|
single chars or single chars in words, clean and difficult sets,
|
||
|
|
formatted texts
|
||
|
|
false negative + false positive
|
||
|
|
start with numbers? option numbers only?
|
||
|
|
output: find fname.{jpg,png} + fname.txt + compare output gocr against txt
|
||
|
|
options: [testpath] [testchars]
|
||
|
|
bin/gocr_chk.sh testbase/free/{clean,glued,dusty}/{numbers,text}/
|
||
|
|
bin/gocr_chk.sh jocr/examples tmp09
|
||
|
|
- fix problem with cutting melted chars (using vector frames)
|
||
|
|
- better detection of agglutinated serifs (Gutenberg scans 086.png+171.png)
|
||
|
|
- vectorize recognition (big step!, relation to other OSS?)
|
||
|
|
(find min distance to ideal vector patterns, start with <>())
|
||
|
|
- frame_nn is marking only the borders like frame_vector and removed later
|
||
|
|
- handle broken and glueed chars by the database algorithm (-m 256 -m 130)
|
||
|
|
- improve get_line2(), implement distance_to_point and distance_to_line
|
||
|
|
- dot-matrix printouts (examples/matrix.jpg) (german: Nadeldrucker)
|
||
|
|
- examples/inverse.pcx + examples/rotate45.pcx by nearest-box-to-line alg.
|
||
|
|
or mean nearest box (or its 4 edges) directions,
|
||
|
|
rotate only boxes (by creating new greater boxes and tread as new image)
|
||
|
|
- proof replacement of getTextLine by getXMLline via pipe(?) or stdout
|
||
|
|
is pipe available on all platforms?
|
||
|
|
- docu about ispell using via XML (what needed, test in gocr.tcl)
|
||
|
|
- replace rest of UNDEFINED in unicode.c by its correct strings
|
||
|
|
- add probability for box->m1..m4 (to reduce errors caused by bad line-scan)
|
||
|
|
call line detection function second time to improve unsure line data
|
||
|
|
|
||
|
|
Next release (0.5x)
|
||
|
|
- reduce pixel data by vectorization (big change, faster)
|
||
|
|
- writing images through pipes (like reading)
|
||
|
|
- using dictionary (optional) for replacing not recognized chars
|
||
|
|
- Karsten.Hilbert@gmx.net: use ORChie WordBox-format
|
||
|
|
see http://http.cs.berkeley.edu/~fateman/kathey/ocrchie.html
|
||
|
|
aspell instead of ispell
|
||
|
|
|
||
|
|
Near future: (planned version)
|
||
|
|
- rewrite install-routine
|
||
|
|
- perspective distortion (for cameras)
|
||
|
|
- genetic algorithms engine (already in development, 0.8?). It includes
|
||
|
|
feature extraction and classification
|
||
|
|
- support for other languages (may affect context_correction(), etc) (0.6?)
|
||
|
|
- support for diagramation. Can be done using the Unicode+new stuff. I (bbg)
|
||
|
|
have some ideas.
|
||
|
|
|
||
|
|
Far future:
|
||
|
|
- gimp plugin
|
||
|
|
- color support
|
||
|
|
- Braille detection (usefull for blinds?)
|
||
|
|
see: American Journal of Physics Vol. 70, No. 7, p 684-688 (2002)
|
||
|
|
or use special foils
|
||
|
|
- read image in smaller parts, to reduce memory usage.
|
||
|
|
- frames should be recognized
|
||
|
|
- better distance function (comparision of characters)
|
||
|
|
- detection of orientation (i.a. 90,180,270deg rotation)
|
||
|
|
- picture extraction
|
||
|
|
- math formula detection, font type detection
|
||
|
|
- handwritten texts (blockletters)
|
||
|
|
--- uff, really a lot of work ---

or tell me, what is the most important point for you.
