A fingerprint from real criminal cases is very reliable forensic *** most problematic fingerprint is still much more reliable than eye witness *** present,the technology of image processing is widely used to deal with low-quality *** different filters to improve the quality of the fingerprint image makes the information provided by the fingerprint is closed to the real information much than before. Moreover,the technology of fragmentary fingerprint image reconstruction is still not mature currently, needing to do the further research on the issues involved.
