Description Ugo Braga Sangiorgi

2010-05-11 19:37:31 EDT

Sketches are relatively big objects, since they hold:
-raw points (x,y) 
-quantized points (only the x,y pairs that matter for recognition)
-sketch's word (the quantized points transformed into a word, for string comparison using Levenshtein string distance)
-location
-size

At the present version, the only attribute that is hold is the word and the element's name, onto a serialized Properties object.
We need a better way of storing sketches, in order to: 
-algorithms to take advantage of the information 
-allow background computation of sketches, since some may take place while the tool is inactive. Ordering, ranking, and so on.

One possible way is to use EMF + XML schema:
