the length of each bound vector is 1), whose initial points are discrete points on the boundary of an object model, and directions are identical to normal vectors of the corresponding initial points with respect to the object boundary.

A record corresponding to each boundary point is a bound vector, whose initial point is the boundary point, and its normal vector, with respect to the boundary of the object.

Each bound vector consists of a boundary point, and its normal vector.

The objective function f measures the summation of the averages of cosine similarity between each bound vector [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] of the transformed model and bound vectors, whose initial points are in its neighboring circle.

The greater the quantity of bound vectors that is chosen, the higher the accuracy of the target shape that can be described.

Exemplars are normalized into the unit square, and lists of derived bound vectors are stored as a prior dataset.

In order to decode informatiom we have to use the operation of unbinding--it is the inverse (an exact inverse or a pseudo-inverse) of binding enabling us to extract an information from a complex statement, provided that we have one of the

bound vectors or a very similar vector as a cue.
