Fingerprint ridge orientation field reconstruction using the best quadratic approximation by orthogonal polynomials in two discrete variables
A novel method for fingerprint ridge orientation field reconstruction is proposed. The original orientation field is estimated using linear projection analysis. A solution to the existent problem of continuous orthogonal polynomials is proposed. 2D discrete orthogonal polynomials for orientation field reconstruction. The proposed method is more accurate and more robust against noise.
