基于Python和openCV的人脸识别研究与实现

Research and implementation of face recognition based on Pythonand opencvAbstractFace recognition technology is to judge whether there is a face in the input image orvideo.If there is a face,the feature data of the face will be obtained,the feature value will becalculated,and the face data will be compared with the existing face data to get the identityinformation of the face.Compared with other biometric technologies,face recognitiontechnology is more convenient and fast.Users do not need to contact with the deviceintentionally or directly,and the device can obtain data by itself.But at the same time,compared with other biometric technology,face recognition technology is more vulnerable toenvironmental interference and errors,which requires human intervention and a large numberof data support.At present,face recognition technology has been widely used in variousscenes at home and abroad.Keywords:Face recognition;biometrics;eigenvalues
