Sketch based retrieval plugin

Retrieving drawings using sketches comprises three main tasks:

The first is automatic indexation of technical drawing databases. To achieve this we have developed techniques to simplify drawings based on their geometric features.

The second task, which constitutes the central component of the information retrieval system, yields methods to match hand-drawn sketches to technical drawings present in the database and associate a measure of similarity to retrieved objects, based on a common symbolic description.

The third task has developed a user interface to query drawing databases and CAD libraries, using hand-drawn sketches.
