Automatic photo grouping by events

摘要

Intuitive photo grouping is accomplished utilizing photo metadata information, including photos' timestamps, GPS information, name and storage folder identity, to automatically generate logical and meaningful event photo groupings for users.

1. A system to perform automated photo grouping of a set of user photos, the system comprising:
a processing unit; and a memory coupled to the processing unit, the memory configured to store instructions that are executable by the processing unit, the processing unit configured to execute the instructions to perform operations comprising:
identify a first user photo associated with a first timestamp, the first timestamp indicating a time at which the first user photo is captured;identify a second user photo associated with a second timestamp, the second timestamp indicating a time at which the second user photo is captured;assign the first user photo to a first event group;compare the first timestamp and the second timestamp to determine whether the second user photo is to be assigned to the first event group, a difference between the first timestamp and the second timestamp being less than a maximum length of time indicating that the second user photo is to be assigned to the first event group, the difference between the first timestamp and the second timestamp being greater than the maximum length of time indicating that the second user photo is not to be assigned to the first event group;assign the second user photo to the first event group, which includes the first user photo, when a difference between the first timestamp and the second timestamp is less than the maximum length of time;assign the second user photo to a second event group that does not include the first user photo when the difference between the first timestamp and the second timestamp is greater than the maximum length of time;assign the first user photo to a first event subgroup of the first event group based on the first user photo being associated with first GPS information, the first GPS information indicating a first location at which the first user photo is captured;determine second GPS information with which the second user photo is associated, the second GPS information indicating a second location at which the second user photo is captured;calculate a distance between the first location and the second location;divide the distance by the difference between the first timestamp and the second timestamp to provide a first distance over time value; andassign the second user photo to the first event subgroup or another event subgroup of the first event group based on the first distance over time value, including:
assign the second user photo to the first event subgroup when the difference between the first timestamp and the second timestamp is less than the maximum length of time and the first distance over time value is less than a maximum distance over time value; andassign the second user photo to a second event subgroup of the first event group when the difference between the first timestamp and the second timestamp is less than the maximum length of time and the first distance over time value is greater than the maximum distance over time value.
