 The segmentation results are in `./128x128/segments_128.tar.gz`. Currently, we have the segmentations of scenes 3100-3199 and 4900-4999 with resolutions 128x128. The shape of all of the images is 1x128x128, and the name of each segmentation is in the form `[scene_id]_[frame_id].png`. The int number in each pixel represents the index of the object (ranges from 1 to 10, and 0 represents the background).
 
-The repository currently contains 128x128 size and 256x256 size datasets, and 640x480 size dataset will be available soon.
