- Subject: proposal estimates for OCR scanning?
- Lines: 29
-
- i am preparing a proposal which needs to include substantial optical
- character recognition (OCR scanning) to capture printed textbook materials into
- a machine-readable format. i need some expertise on what expenses to plan for.
- the project will collect all reading assignments for students in a class and
- then scan in as much as we can per month for statistical analysis of the
- material.
-
- as i understand the process, we scan text in a fixed font and then have to
- hand-correct errors in the range of 5-10 characters per 1000. this then needs
- a third pass to verify the correction. result is about 1 char per 100K error.
- through-put rate is about the same as hiring a skilled secretary (55 wpm) to
- type in the text, reading from the hardcopy. (secretary is without dual
- reading for 1/100K verification). from this, can i estimate that 2 graduate
- students (20 hr per week) could process about 200M per 9 month academic year?
-
- can i assume that a 486 cpu with 10M ram is adequate engine for OCR? what
- scanner and software expenses should i request? hand-held or flatbed? i have
- heard that OCR is prone to mechanical downtime. would 2 sets of OCR hardware
- per cpu be adequate to keep the process moving?
-
- now, how much a wrinkle will it be to do this in russian (or other
- indoeuropean languages) rather than english?
