A spatial domain scar removal strategy for fingerprint image enhancement
作者：
Highlights：
• We Model a new proposed method to make use of the Fourier domain directional field to trace an appropriate candidate for the scar pixels to be replaced with.
• The necessary components of the process are locating scars, finding the directional field, and the filling strategy.
• The strategy relies on the fact that in these linear scars, the ridge/valley pattern is still intact across the scar region.
• Using this information, the scar boundary is filled with appropriate normal region pixels using the local orientation field.
• This process can act as front-end to the subsequent Gabor and anisotropic diffusion filtering.
