摘要
人脸识别技术在公安领域内已经取得了一定的成绩,通过主成分分析法、梳理投影图和特征描述相匹配法、面部对称处理还原法、等测地区域的三维面貌相似度评价法、构建隐马尔科夫模型等破获了多起案件。但在应用过程中,一些难题也更充分地显露出来,主要包括某些算法固有的缺陷被放大、理论研究与现实运用存在差距、缺乏专门的技术人员进行人脸识别系统研发与操作等。为构建以人脸识别技术为基础的公安工作系统,必须不断研发与改进算法,提高识别率;同时需要与其他技术相结合,提高严谨性,改善硬件条件以提供支撑,促进理论研究与实践应用的衔接,提高执法人员进行研发与操作的素质。
The face recognition has made certain achievements in the practice of public security,which has used the methods of the principal component analysis,projection drawing and characterization matching,facial symmetry restoration,3D face similarity evaluation within iso-geodesic regions and hidden markov model.Some conundrums have been exposed more clearly,including inherent flaw of some algorithms,being magnified,gap between theoretical research and practical use,lack of specialized technical personnel for research and development and operation of the face recognition system.In order to build a complete and advanced public security system based on face recognition,the tasks such as developing algorithms to increase recognition rate,combining into other bio-recognizable technologies to enhance stringency,improving the hardware conditions to provide support,promoting convergence of theory research and practical application and training a team of specialized technical personnel along with improving the expertise and operational skills of the involving police-persons should be done.
