摘要：#$%^&*AU2016208411A120170420.pdf##### ABSTRACT Systems and methodsfor identifying shapes (e.g., shapes corresponding to objects or persons) in an imagecomprising: identifying an unknown shape represented by a Bezier path, the Bezier pathcomprising at least one Bezier curve; identifying a known shape represented by a storedBezier path, the stored Bezier path comprising at least one stored Bezier curve;determining, by at least one processor, a matrix transformation that transforms the atleast one Bezier curve of the unknown shape to the at least one stored Bezier curve ofthe known shape; applying the matrix transformation to the at least one Bezier curve ofthe unknown shape; and comparing the transformed at least one Bezier curve of theunknown shape to the at least one stored Bezier curve of the known shape to determinewhether the unknown shape matches the known shape. 6/7 600 610 Identifying AnUnknown Shape 620 Identifying A Known Form Element Represented By A Stored B6zierPath 630 Determining A Matrix Transformation 0 Applying The Matrix TransformationComparing The Transformed Bezier Path To The Stored Bezier Path 650 To Determine AMatch Applying Properties Associated With The Known Form Element 660 To TheUnknown Shape Fig. 6
