Claim One:
1. A computer system comprising one or more processors, one or more computer-readable memories, and one or more computer readable storage mediums having computer readable program code stored therein, said program code executable by at least one of the one or more processors via at least one of the one or more computer-readable memories to implement a method comprising: capturing a first set of images during a first traversal of a first route; capturing a second set of images during a second traversal of the first route; identifying, by comparing the first set of images with the second set of images, an object in the second set of images meeting an obstruction criteria; and providing a notification of the object which was identified as meeting the obstruction criteria; wherein said capturing the first set of images during the first traversal of the first route includes: collecting route frequency data for a set of routes traversed by a user; determining, for a specific route of the set of routes traversed by the user, that a frequency value is greater than a frequency threshold value; and selecting, in response to determining that the specific route has the frequency value greater than the frequency threshold value, the route as the first route.
