SHAPE RECOGNITION USING PARTIAL SHAPES

摘要

Shape recognition is performed based on determining whether one or more ink strokes is not part of a shape or a partial shape. Ink strokes are divided into segments and the segments analyzed employing a relative angular distance histogram. The histogram analysis yields stable, incremental, and discriminating featurization results. Neural networks may also be employed along with the histogram analysis to determine complete shapes from partial shape entries and autocomplete suggestions provided to users for conversion of the shape into a known object.

主权项

1. A method for shape recognition, comprising:
receiving ink entry comprising at least one stroke that is a partial shape; displaying the ink entry on the display; displaying a suggested completion for the ink entry that shows a complete shape that is based on the received ink entry; and after displaying the suggested completion for the ink entry, converting the ink entry to the complete shape when determined.
