AMOS: Archive of Many Outdoor Scenes

view other research projects.


The Archive of Many Outdoor Scenes (AMOS) dataset contains more than 20 million images taken from over 500 webcameras 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, with the majority being 320 x 240.

A montage image created from all the images from a single camera. Rows of images correspond to the time of year and columns of images correspond to the time of day.
A montage of false-color images created using principal component analysis.

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.

Scene Montage Images

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.

Dataset Access

Several subsets of AMOS are available for experimenation: The dataset details page contains information about obtaining the complete dataset.
