OBJECT RECOGNITION CACHE

摘要

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for storing facial recognition image data in a cache. One of the methods includes receiving an image from a camera, detecting, in the received image, a face of a person, searching a biometric data cache based on the detected face, in response to searching the biometric data cache based on the detected face, determining whether the biometric data cache includes data for the person, in response to a determination that the biometric data cache includes data for the person, using the data from the biometric data cache to determine an identifier for the person, and in response to a determination that the biometric data cache does not include data for the person: searching a data storage system based on the detected face of the person to determine whether the data storage system includes data for the person.

主权项

1. A system comprising:
a data storage system configured to maintain, for a first group of multiple different people, biometric data for each of the multiple different people; a biometric data cache configured to maintain, for a second group of multiple different people that is different than the first group, image data for each person in the second group, each person in the second group having at least a threshold likelihood of being within a field of view of a camera; a data processing apparatus; and a non-transitory computer readable storage medium in data communication with the data processing apparatus and storing instructions executable by the data processing apparatus and upon such execution cause the data processing apparatus to perform operations comprising:
receiving an image from the camera;detecting, in the received image, a face of a person;searching the biometric data cache based on the detected face of the person;in response to searching the biometric data cache based on the detected face, determining whether the biometric data cache includes data for the person;in response to a determination that the biometric data cache includes data for the person, using the data from the biometric data cache to determine an identifier for the person; andin response to a determination that the biometric data cache does not include data for the person:
searching the data storage system based on the detected face of the person to determine whether the data storage system includes data for the person; andstoring image data for the person in the biometric data cache.
