It's a neat trick: instead of trying to work with the (x,y) points of a gesture, and worrying about rescaling/translating to match, it resamples the template and gesture into n vectors each with the same length, and the comparison is then just the sum of the angle differences in corresponding vectors in the two lists.
- crusso 11y agoSo, gestures that involve strokes radially outward or inward might be fairly difficult to distinguish?
- bazzargh 11y agoI imagine it would have difficulty with letters that differ only in scale (x, X) but for things like varying stroke order, stroke direction to achieve the same mark - which is I think what you're getting at? - the paper suggests just recording more templates for the glyph works well.
