+# PASCAL VOC and SBD
+
+PASCAL VOC is a standard recognition dataset and benchmark with detection and semantic segmentation challenges.
+The Semantic Boundary Dataset (SBD) is a further annotation of the PASCAL VOC data that provides more semantic segmentation and instance segmentation masks.
+
+PASCAL VOC has a private test set and [leaderboard for semantic segmentation](http://host.robots.ox.ac.uk:8080/leaderboard/displaylb.php?challengeid=11&compid=6).
+
+The train/val/test splits of PASCAL VOC segmentation challenge and SBD diverge.
+Most notably VOC 2011 segval intersects with SBD train.
+Care must be taken for proper evaluation by excluding images from the train or val splits.
+
+We train on the 8,498 images of SBD train.
+We validate on the non-intersecting set defined in the included `seg11valid.txt`.
+
+Refer to `classes.txt` for the listing of classes in model output order.
+Refer to `../voc_layers.py` for the Python data layer for this dataset.
+
+See the dataset sites for download:
