The Hopkins 155 Dataset has been created with the goal of providing an extensive benchmark for testing feature based motion segmentation algorithms. It contains video sequences along with the features extracted and tracked in all the frames. The ground-truth segmentation is also provided for comparison purposes. The data is stored in the .MAT file format.
Our dataset contains sequences with two and three motions. The sequences can be roughly divided into three categories:
|2 Motions||3 Motions|
|# Seq.||Points||Frames||# Seq.||Points||Frames|
|Some samples from the Hopkins 155 dataset|
We provide 16 additional sequences that contain missing data or both missing data and outliers and more than three motions. These sequences have the same format and complement the standard Hopkins 155 dataset. We call the aggregated dataset Hopkins 155+16. These sequences can be downloaded from the Download section below.

We collected the results obtained on the Hopkins 155 dataset by various motion segmentation algorithm presented in the literature. Please see the corresponding section in the Motion Segmentation research page
