No face recognition program can achieve 100% accuracy, which is a foreseeable problem that will exist for a long time to come. Recently, the South Wales police revealed in a record request that the automatic face recognition (AFR) "positioning" system used in the remaining events of the 2017 Champions League finals, the turnover rate of more than 90%. It is reported that the South Wales police originally intended to carry face recognition technology in a closed-circuit television monitoring system at a specific location or vehicle, based on a database of 500,000 person images to check and identify the participants. However, in the later investigation, the police found that the system marked a total of 2,470 people, of which 2,297 people misjudged and only 173 people were correctly matched. According to the South Wales police, these “false positives†are due to the poor quality of the pictures provided by other agencies, and there is currently no face recognition procedure that can achieve 100% accuracy, which is a foreseeable and in the future. A problem that will exist for a long time. In addition, the police also believe that despite a large number of misjudgments, this face recognition project has achieved "great success" and the accuracy rate has increased a lot. Over the past nine months, they have achieved 2,000 correct matches and conducted 450 arrests based on this information. Next, the police will continue to conduct in-depth research in this area to raise the accuracy rate to a satisfactory level as soon as possible. 110V Gear Motor,Ac Motor Low Rpm,Customized Ac Gear Motor,Customized Ac Geared Motor NingBo BeiLun HengFeng Electromotor Manufacture Co.,Ltd. , https://www.hengfengmotor.com
