近年来,指纹自动识别系统在我国得到了较大的发展,在侦查破案、打击犯罪中发挥了不可替代的作用。指纹识别系统是根据指纹特征的一般规律特点编制的软件,利用指纹系统进行检索比对,必须对现场指纹及十指指纹进行人工干预。1现场指纹的人工干预1.1必要性现场指纹由于受作用力、介质、承痕客体等各种因素的影响,往往条件较差,多是纹线不太清晰或残缺不全甚至变形严重,这就要求我们必须对现场指纹的特征点标注进行
In recent years, the automatic fingerprint identification system has been greatly developed in our country, playing an irreplaceable role in the investigation and the crackdown of crimes. Fingerprint identification system is based on the general characteristics of the characteristics of fingerprints compiled software, the use of fingerprint system for retrieval comparison, must be on-site fingerprints and fingerprints for manual intervention. 1 field fingerprinting manual intervention 1.1 Necessity Field fingerprints due to force, media, bearing objects and other factors, often poor conditions, mostly lines are not clear or incomplete incomplete or even serious deformation, which requires We must mark the feature points of the field fingerprinting
