Abstract
Newly acquired fingerprint images have a lot of noise. This article use BEMD decomposes the fingerprint image. Each of the IMF obtained represents a particular scale. To some extent, it reflects the image texture information at different scales. The proposed algorithm use two-dimensional empirical mode decomposition to resolve the fingerprint image into a series of IMF and the residual. Take into account the distribution of noise between each component, the method use selected components to synthesis fingerprint image. It eliminates the effect of noise and enhance fingerprint image effectively.
