processing. In such sequential processing, however, the
segmentation processing took place with limited information,
without reference to context information that could help in
determining the most likely characters. Commencing with
characters determined by a segmentation process based on
limited information, moreover, correspondingly hindered the
accuracy of the context processing.
The invention at issue in this appeal integrates
segmentation and context processing into a two-pass searching
process. First, a dynamic programming path search performs
all the segmentation processing and most of the context
processing while the user is still writing. Accordingly, the
context processing is not delayed until after all ink data are
collected. Second, a stack-based path search completes the
context processing after all the ink data are received.
Claim 1, which is representative for our purposes,
follows:
1. A method of processing data that represents strokes
of handwritten information, thereby to identify characters
represented by the data, the method comprising the steps of:
