作者：
Highlights：
• 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.
