The Algorithm of Fingerprint Enhancement base on Dynamic Direction Field

摘要：

In this paper,we studied the algorithms offingerprint image enhancement and put forward a newmethod to calculate the direction image.Firstly,RadonTransform is used to estimate the direction image,then,the image is filtered by a set directional filters,thus,weget the enhanced image.The experiment resultsindicate that this method is simple and efficient;whichestablished the firmed foundation to fingerprint imagematching.
