Compare protos p1 and p2 and return an estimate of the worst evidence rating that will result for any part of p1 that is compared to p2. In other words, if p1 were broken into pico-features and each pico-feature was matched to p2, what is the worst evidence rating that will be achieved for any pico-feature.

This routine computes a proto which is the weighted average of protos p1 and p2. The new proto is returned in MergedProto.
p1,p2 | protos to be merged |
w1,w2 | weight of each proto |
MergedProto | place to put resulting merged proto |

void ComputePaddedBoundingBox | ( | PROTO | Proto, |
float | TangentPad, | ||
float | OrthogonalPad, | ||
FRECT * | BoundingBox | ||
) |
This routine computes a bounding box that encloses the specified proto along with some padding. The amount of padding is specified as separate distances in the tangential and orthogonal directions.
Proto | proto to compute bounding box for | |
TangentPad | amount of pad to add in direction of segment | |
OrthogonalPad | amount of pad to add orthogonal to segment | |
[out] | BoundingBox | place to put results |

This routine returns true if Feature would be matched by a fast match table built from Proto.
Feature | feature to be "fast matched" to proto |
Proto | proto being "fast matched" against |

This routine searches through all of the prototypes in Class and returns the id of the proto which would provide the best approximation of Prototype. If no close approximation can be found, NO_PROTO is returned.

This fills in the fields of the New proto based on the fields of the Old proto.
