Identifying items in images

1. A computer-implemented method comprising:

receiving, from a device, (i) an image, and (ii) device location data;

determining, based on the device location data, that a particular set of one or more store locations are within a threshold distance of the device;

accessing, for each of the one or more store locations in the particular set, item information that indicates one or more items that are designated as being eligible for retrieval at the store location;

determining, based on the accessed item information, that the image likely shows a particular item that is designated as being eligible for retrieval at one or more store locations in the particular set;

determining, for each of the one or more store locations at which the particular item is designated as being eligible for retrieval, a predicted amount of time that a task of retrieving one or more items at the store location would take;

ranking the one or more store locations based at least on the predicted amounts of time;

generating a set of instructions for presentation of information about (i) the particular item and (ii) one or more store locations in the particular set, ordered based on the ranking, at which the particular item is designated as being eligible for retrieval; and

providing, to the device, the generated set of instructions for presentation of information about (i) the particular item and (ii) the one or more store locations in the particular set at which the particular item is designated as being eligible for retrieval.

accessing, for each of the one or more store locations in the first set, item information that indicates one or more items that are designated as being eligible for retrieval at the store location;

determining, based on the accessed item information for the one or more store locations in the first set, that the image does not satisfy a threshold likelihood for any of the one or more items that are designated as being eligible for retrieval at the one or more store locations in the first set; and

in response to determining that the image does not show any of the one or more items that are designated as being eligible for retrieval at the one or more store locations in the first set, identifying a second threshold distance that is greater than the first threshold distance, wherein determining, based on the device location data, that the particular set of one or more store locations are within the threshold distance of the device's physical location comprises:

after identifying the second threshold distance, determining, based on the device location data, that a second set of one or more store locations are within the second threshold distance of the physical location of the device, the second set of one or more store locations being different from the first set of one or more store locations.

7. The method of claim 1 , further comprising:

determining, based on the device location data, that the device is located within a geographic region that is occupied by a particular venue or park, wherein determining, based on the device location data, that the particular set of one or more store locations are within the threshold distance of a physical location of the device comprises:

determining, based on the device location data, that the particular set of one or more store locations are (i) within the threshold distance of the device's physical location, and (ii) positioned within the geographic region that is occupied by the particular venue or park.

8. The method of claim 7 , further comprising:

determining that the device is associated with a particular user; and

accessing user information indicating one or more characteristics of the particular user and a visit to the particular venue or park by the particular user.

9. The method of claim 1 , further comprising:

for each item that is associated with one or more store locations in the particular set, accessing, based on the accessed item information, imaging data that is associated with the item; and

evaluating the image against the accessed imaging data.

10. The method of claim 1 , further comprising:

after providing, to the device, instructions for presentation of information about (i) the particular item and (ii) one or more store locations in the particular set, receiving, from the device, data indicating a user selection of a particular one of the one or more store locations indicated in the instructions; and

in response to receiving data indicating the user selection of the particular store location, providing, to one or more devices that are associated with the particular store location, instructions for presentation of a notification about the particular item.
