METHOD, APPARATUS AND COMPUTER READABLE RECORDING MEDIUM FOR MANAGING A REFERENCE FACE DATABASE TO IMPROVE FACE RECOGNITION PERFORMANCE UNDER A RESTRICTED MEMORY ENVIRONMENT

摘要

An embodiment of the present invention presents a method for managing a reference face database to improve face recognition performance under a restricted memory environment, said method comprising: a step of acquiring a new input face image; a step of determining a classification condition corresponding to the input face image with reference to classification conditions of existing registered face images of a reference face database used for face recognition; and a step of, if the classification condition corresponding to the input face image is a specific classification condition and the value of the face image corresponding to the specific classification condition in the reference face database is less than a preset threshold value, selecting the input face image as an image which can be additionally registered to the reference face database.
