Time-lapsed image sequence generation

摘要

Aspects of the disclosure relate to providing users with sequences of images of physical locations over time or time-lapses. In order to do so, a set of images of a physical location may be identified. From the set of images, a representative image may be selected. The set may then be filtered by comparing the other images in the set to the representative image. The images in the filtered set may then be aligned to the representative image. From this set, a time-lapsed sequence of images may be generated, and the amount of change in the time-lapsed sequence of images may be determined. At the request of a user device for a time-lapsed image representation of the specified physical location, the generated time-lapsed sequence of images may be provided.

主权项

1. A method for generating and providing time-lapsed sequences of images, the method comprising:
identifying, by one or more computing devices, a set of images of a physical location; selecting, by the one or more computing devices, a representative image of the set of images; filtering, by the one or more computing devices, the set of images by comparing each image of the set of images to the representative image; aligning, by the one or more computing devices, the images of the filtered set of images to the representative image; generating, by the one or more computing devices, a time-lapsed sequence of images based on the aligned filtered set of images; determining, by the one or more computing devices, a first value for the time-lapsed sequence of images based on changes in pixel values from one image in the sequence to the next image in the sequence at corresponding pixel locations; and in response to a request from a user computing device for a time-lapsed image representation of the physical location, providing, using the one or more computing devices, the time-lapsed sequence of images when the first value exceeds a threshold.
