3D fingerprint acquisition using coloured photometric stereo

Abstract

This chapter details on more efficient 3D fingerprint imaging approach using coloured photometric stereo based approach. This approach is introduced to address two key problems associated with practical 3D fingerprint imaging: involuntary finger motion and computational complexity for online applications. This method detailed in this chapter results from revisiting the classical photometric approach. This chapter also introduces shapelets correlated-based approach for 3D fingerprint reconstruction with comparative evaluation of mean squared error from reconstructed images. This chapter also presents a comparative analysis of the influence of finger surface contamination on the 3D and 2D fingerprint images.
