Can someone give me references and/or a summary of what the state-of-the-art
is in handwriting recognition? I have seen a few informal references in the
past, but they are (I'm sure) outdated now. I'm looking into how far
research has come in the last couple years and where it is today.
I'm interested in both "trained" systems (system is trained to recognize a
specific person's handwriting) and general systems (intended to be able to
read anyone's handwriting without training). I'm mostly interested in
software that will run on a small system like a 286/386 PC (MS-DOS) or a small
workstation (UN*X), but I'd like to know the state-of-the-art in bigger
engines as well. And I'm interested in systems that will do the character
interpretation either in real-time or offline. I'm wondering:
1) What are typically accepted success rates (e.g., recognizes
characters correctly 90% of the time)?
2) [For trained systems] What are typically accepted numbers
for how many times a character has to be repeated to train
the system?
3) What kind of media is generally used to enter handwriting
(e.g., digitizer for real-time or scanner for non-real-time)?
4) Any systems designed to recognize "longhand" or "cursive"
writing (I assume most are designed for printed characters)?
5) Any references (recent) to theory and practice, including
discussing things like what you do when you can't recognize
a specific character?
6) What systems are commercially (or free/shareware) available?
7) Has the business world started using any handwriting
recognition in real live applications?
If anyone has any info or pointers, I'd appreciate it. Thanks.
