Abstract

The application discloses a progressive judgment update method, device and face check-in system. Among them, the method includes: obtaining the first picture with the highest score among the face pictures obtained by the user through the face check-in system within the first period of time, the score is obtained by calculating the similarity between the face picture and the bottom database picture, and when the score is greater than or equal to the check-in threshold, determine that the check-in is successful; calculate the average score of the similarity calculation between the first picture and all the user's bottom library pictures, and obtain the first mean; calculate the first picture and the user to remove the lowest score The average value of the similarity calculation scores of the remaining bottom library pictures after the bottom library pictures is used to obtain the second average value; the check-in threshold is updated based on the difference between the second average value and the first average value. Using this method, the face check-in system can adjust the check-in threshold according to the face pictures obtained during the user's check-in process, so as to realize the gradual increase of the check-in threshold and continuously improve the accuracy of face recognition.

Description

Technical field [0001] The present application relates to the field of image processing, and in particular, to a progressive judgment update method, device and a face card system. Background technique [0002] Strictly regulate employee card attendance is an important guarantee for the improvement of management efficiency in modern enterprises and institutions, and traditional cards, credit cards, etc. There are existence cards, low efficiency, and non-statistical, management and maintenance costs. The fingerprint identification product, although it can partly solve problems such as generation card, but more than 5% of people are very shallow, and they cannot use fingerprint identification, and they must contact the machine, and provide a convenient carrier to bacterial propagation. [0003] With the development of deep learning technology, the accuracy of the camera is improved, the cost is reduced, and the technology of the face recognition is increasingly mature, and it has qu...
