#$%^&*AU2016208411A120170420.pdf#####ABSTRACT Systems and methods for identifying shapes (e.g., shapes corresponding to objects or persons) in an image comprising: identifying an unknown shape represented by a Bezier path, the Bezier path comprising at least one Bezier curve; identifying a known shape represented by a stored Bezier path, the stored Bezier path comprising at least one stored Bezier curve; determining, by at least one processor, a matrix transformation that transforms the at least one Bezier curve of the unknown shape to the at least one stored Bezier curve of the known shape; applying the matrix transformation to the at least one Bezier curve of the unknown shape; and comparing the transformed at least one Bezier curve of the unknown shape to the at least one stored Bezier curve of the known shape to determine whether the unknown shape matches the known shape.6/7 600 610 Identifying An Unknown Shape 620 Identifying A Known Form Element Represented By A Stored B6zier Path 630 Determining A Matrix Transformation 640 Applying The Matrix Transformation Comparing The Transformed Bezier Path To The Stored Bezier Path 650 To Determine A Match Applying Properties Associated With The Known Form Element 660 To The Unknown Shape Fig. 6
