Interpretation Tree

This page includes a Java applet that allows you to experiment with the interpretation tree search algorithm. A description of the algorithm may be found on the MARBLE project pages.

The applet screen is divided into three areas:

You will probably find that you need to maximize your browser window in order to see the complete applet. In order that you may still refer to the instructions, click the middle button here. Below the applet there is a summary of the controls.

Colours: white: matched features, pink: ``wildcard'' matches, blue: unmatched features, red: current node.

Controls

Image Window

The image window shows the model being searched for on the left and a scene containing the model on the right. The lines have been extracted by an edge detection and corner-finding process.

Tree Window

The tree window draws the tree display, automatically resizing the tree to fit as much as possible in the window. Dragging the window allows other parts of the tree to be displayed.
