Abstract

In an approach to establishing personal identity using multiple sub-optimal images, a method includes receiving a set of sub-optimal input images, identifying a first and a second user feature in the set of sub-optimal input images, and determining a confidence score of the user features by comparison to user profile images. The method additionally includes determining a combined confidence score of the first user feature and the second user feature and determining whether features match a user by: (i) determining whether the combined confidence score is higher than a pre-determined threshold for the combined confidence score, (ii) determining whether the confidence score of the first user feature is higher than a pre-determined threshold for the user features, and (iii) determining whether the confidence score of the second user feature is higher than the pre-determined threshold for the user features.

Dependent claims

A method comprising:

receiving, by one or more processors, a set of sub-optimal input images corresponding to a period of time, wherein each input image in the set of input images corresponds to a specific time within the period of time;
identifying, by one or more processors, a first user feature in the set of sub-optimal input images;
determining, by one or more processors, a confidence score of the first user feature by comparison of the first user feature to one or more user profile images;
identifying, by one or more processors, a second user feature in the set of sub-optimal input images;
determining, by one or more processors, a confidence score of the second user feature by comparison of the second user feature to one or more user profile images;
determining, by one or more processors, a combined confidence score based on the confidence score of the first user feature and the confidence score of the second user feature;
and
determining, by one or more processors, whether the first user feature and the second user feature match a user by:
(i) determining the combined confidence score is higher than or equal to a pre-determined threshold for the combined confidence score, (ii) determining the confidence score of the first user feature is higher than or equal to a pre-determined threshold for the user features, and (iii) determining the confidence score of the second user feature is higher than or equal to the pre-determined threshold for the user features.
