Information about the AMOS Dataset
The Archive of Many Outdoor Scenes (AMOS) dataset contains more than 90 million images taken from over 12,000 webcams located around the world, the vast majority in the United States. Construction of AMOS began in March, 2006 and continues to this day. This dataset is unique in that it contains images from significantly more scenes than in previous work.
The cameras in the dataset were selected by a group of graduate and undergraduate students using a standard web search engine. Images from each camera are captured several times per hour using a custom web crawler that ignores duplicate images and records the capture time. The images from all cameras are 24-bit JPEG files that vary in size from 316 x 240 to 2048 x 1536.
Locations of the cameras in AMOS that are located in the continental United States.
We created a large number (currently 170) of montage images that summarize a year of images of a scene. More are available via the AMOS flickr collection.
Why collect so many images?
One impetus for collecting these images was to provide a dataset to enable empirical assessment of our ideas regarding the statistics of natural scenes captured from static cameras. These statistics have not been well studied and are of great importance to surveillance algorithm and application development.
The dataset is available in two ways:
- Through the camera browser, which lists details about each individual camera, as well as an interface to browse the many years of imagery we have archived.
- A .zip file archive, where you can download many months of imagery at a time for experimentation. If you plan to download a substantial amount of the AMOS dataset, follow these steps:
- Download the following script: download_amos.py.
- Open the file in your favorite text editor.
- Edit the constants CAMERAS_TO_DOWNLOAD, YEARS_TO_DOWNLOAD, and MONTHS_TO_DOWNLOAD for the segments of the dataset you care about.
- Run using "python download_amos.py"
- The files should now start downloading and extracting in your current directory.
There is also a dataset that contains the above, with some ground truth geolocation labels, for use in image geolocation algorithms.Please cite the following if you use AMOS in your work:
