Computer Graphics Analysis: A Method for Arbitrary Image Shape Description

─ A concept of a new set of features suitable for describing arbitrary shapes after their thinning is presented. The features are the minimal eigenvalues of the Toeplitz matrices formed from the rational functions, in which the coordinates of the characteristic pixels of the shape to be described are used as coefficients, the x coordinates in the numerator polynomial, and the y coordinates in the denominator polynomial. The rational function has a form which makes it a general measure of Image description and its features extraction. The method is introduced and applied for the first time.
