Package containing helper functions for loading and evaluating DAVIS.

A Matlab version of the same package is also available.

DAVIS (Densely Annotated VIdeo Segmentation), consists of fifty high quality, Full HD video sequences, spanning multiple occurrences of common video object segmentation challenges such as occlusions, motion-blur and appearance changes. Each video is accompanied by densely annotated, pixel-accurate and per-frame ground truth segmentation.

Please cite DAVIS in your publications if it helps your research:
