Chinese handwriting recognition

Question

I'm looking for handwriting recognition solution. I've found one here, which is a flash application. What's the principle of how it works? Does it make any queries to db to find the character?

Answer 1

Have done this once for japanese (includes chinese character set). I had divided the operation in 4 steps, repeated at each stroke:

1. Count the number of total strokes

2. Determine Stroke order (the order of each stroke is important)

3. Determine stroke start and end radian (notice the drawing space is divided in radians)

4. Narrow down database matches, based on the above results.
