I'm training Tess to recognize letters/numbers/symbols/etc. used for geometrical tolerancing and annotations (ASME Standard Y14.5) Alot of the characters used in the ASME standard are coming from all over the unicode tables (although the characters/words are from the English language).
This is part of a data validation project and I'm using OCR as part of the process. Since OCR is not 100% accurate, some of the validation will need to be done by hand (hopefully as little as possible). If the person checking the annotation sees a "little box" (ie unprintable character) then it will slow down their job. For the moment, I check unprintable characters using the webapp which I posted above. Once this goes into production, there will be a font (purchasd or home- brewed) which can correctly draw all the letters/numbers/symbols/etc. On May 2, 7:04 am, 74yrs old <[email protected]> wrote: > Hi Rob, > I know about conversion.php which I am using for long time for Kannada > project. > Will you kindly explain by step by step of your experiment with sample if > any.
