Abstract： |
The invention relates to a fingerprint identification method based on the density diagram model, which belongs to the fingerprint identification technique field. Its characteristic is shown as the following. The method combines the conventional detail point characteristic with the effective region characteristic and the density diagram characteristic to give the fingerprint identification characteristic. At the same time, combines the density diagram comparison result with the conventional detail point comparison result to improve the identification rate. The method is applicable with a little increment of the needed memory spaces. It is more suitable to identify the poor quality fingerprints. |
