Method for assessing quality of human facial images in facial recognition application, involves classifying quality of image by classifying that image has quality same as that of previously classified image related to smallest difference

摘要

The method involves computing a difference between a tonal distribution of a human facial image and a tonal distribution of each of multiple previously classified images. A smallest computed difference between the tonal distribution of an image and the tonal distribution of the previously classified image is determined based on the computed differences. A quality of the image is classified by a mobile computing device (200) e.g. mobile phone, by classifying that the image has a quality same as that of the previously classified image related to the smallest computed difference. Independent claims are also included for the following: (1) a computer-readable storage device storing a program comprising a set of instructions for assessing quality of facial images (2) a mobile computing device.
