Claim:
1. In a digital medium environment for analyzing and classifying images, a method for identifying a shape in an image, comprising: identifying an unknown shape within an image represented by a Béziér path, the Béziér path comprising at least one Béziér curve; identifying a known shape represented by a stored Béziér path, the stored Béziér path comprising at least one stored Béziér curve; determining, by at least one processor, a matrix transformation that transforms the at least one Béziér curve of the unknown shape to the at least one stored Béziér curve of the known shape, wherein the matrix transformation accounts for a change in scale and a change in skew between the at least one Béziér curve and the at least one stored Béziér curve; applying the matrix transformation to the at least one Béziér curve of the unknown shape; comparing the transformed at least one Béziér curve of the unknown shape to the at least one stored Béziér curve of the known shape to determine whether the unknown shape matches the known shape; and classifying the image based on the comparison of the at least one Béziér curve of the unknown shape to the at least one stored Béziér curve of the known shape.
