MPI Sintel Segmentation Training Data


Download data (90 MB)

Note of caution

This is the beta version of the dataset, and might change in the near future. We will keep registered users up-to-date, but please make sure to check this page for the latest version.

The test set and an evaluation website will be available in May 2015.




What is in the archive?


This archive contains the beta version of the Sintel-segmentation training set. For each of the training sequences, it contains:


The segmentations

Here, we define a segment to be a set of pixels that (a) share the same material, and (b) belong to the same mesh. The labels of all segments are consistent across all frames of a given sequence, but not necessarily across different sequences.

A visualization of the segmentations is also included.


Masks of invalid pixels / segments

Due to aliasing effects, some segments are only a few pixels large. Therefore, we mask out all segments which are smaller than 25 pixels in all frames of a given sequence.


SDK

The SDK includes example scripts to read/write the segmentation data, and documentation on the data format.




How was it generated?


The dataset was generated by assigning unique IDs to each mesh and each material in Blender, and writing them out via the object and material passes. The final labels are a combination of these two unique IDs.

To generate the mask of invalid segments, we mark all segments for which the maximum size over the whole sequence never exceeds 25 pixel.




Examples


These example show the final pass with superimposed segment boundaries (top) and the color-coded segmentation (bottom).
