Boundary analyzer

An apparatus for measuring deviations in an object boundary of an object within an image, the apparatus comprising:

• an index device adapted to generate a first set of first segments, each first segment having indexed first vertices and a class, the first set representing a first boundary of the object, and the index device also being adapted to generate a second set of second segments, each second segment having indexed second vertices, the second set representing the object boundary of the object;
• a matching device, cooperative with the index device, adapted to substantially match at least some of the second vertices to at least some of the first vertices so as to produce matched second segments, each matched second segment associated with a class of matched first segments;
• and
• an analyzer, cooperative with the matching device, adapted to measure deviations in at least some of the second segments having the matched second vertices using the class associated with the matched second vertices and the data points of the second segments.

A method for analyzing an object boundary of an object within an image, the method comprising:

• a. generating a set of first segments each having indexed first vertices, the set representing a first boundary of the object;
• b. generating a set of second segments each having indexed second vertices representing the object boundary of the object;
• c. substantially matching at least some of the second vertices to at least some of the first vertices so as to produce matched second and first segments;
• d. refining the segmentation of unmatched second segments to match with unmatched first segments so as to produce additional matched second and first segments;
• and
• e. analyzing the object boundary of the object using the matched second and first segments.

A method for measuring deviations in an object boundary of an object within an image, the method comprising:

• providing a first set of first segments, each one of the first segments having indexed first vertices and a class, the first set representing a trained boundary of the object;
• providing a second set of second segments, each one of the second segments having indexed second vertices, the second set representing the object boundary of the object in the image;
• substantially matching at least some of the indexed second vertices with at least some of the indexed first vertices so as to produce matches for at least a portion of the second segments, each of the matches including at least two of the indexed first vertices, and each of the matches being associated with the class of the one of the first segments having the respective at least two of the indexed first vertices;
• and
• measuring deviations within each of the at least a portion of the second segments of the matches using the respective class associated with each of the matches.
