ETCHA Sketches
This is the home of the Experimental Test Corpus
of
Hand Annotated Sketches (ETCHA Sketches). It is a
collection of
sketches collected on a Tablet PC and a set of annotations for many of
the strokes. The annotations currently are labellings of
individual strokes as primitive shapes: line, arc, ellipse, polyline,
polygon,
and other. The sketches are drawn from four domains: simple geometric
figures, circuit diagrams, floor plans, and family trees.
The possible uses of this data include (but should by no means be
limited to) training and testing of recognition systems and exploring
properties of naturally drawn sketches.

This will help others to obtain the same data sets and replicate your
experiments. Thank you.
