Combining implicit polynomials and algebraic invariants for representing and recognizing compli-
cated objects is proven to be a powerful technique. There are several methods in the literature for determining
algebraic invariants from the implicit polynomial coefficients of 2D curves under Euclidean, affine, and projec-
tive transformations. In this paper, we compare the performance of these invariants for object recognition using
a database comprising 337 Turkish carpet designs.
