Abstract :
This article systematically elaborated the correlation theories of fingerprint recognition technology and several essential algorithms. Combining the characteristic of fingerprint image in the pretreatment process, key technologies of fingerprint pretreatment have been studied, including fingerprint image intensification which is based on the gradation standardization, the directional diagram and filter, uses the auto-adapted algorithm based on partial smooth threshold value to carry on the binaryzation. The experimental result indicates that the processing effect is good.
