NYU Depth v2 Segmentation Tools

The below repository contains MatLab tools to pre-process the segmentation ground truth provided as part of the NYU Depth v2 dataset. As illustrated in Figure 2, the ground truth is processed to remove thin unlabeled parts that are problematic for evaluation.

The original NYU Depth v2 dataset is required and can be found here.

Usage overview:

• convert_dataset.m: Used to split the dataset into training and test set according to list_train.txt and list_test.txt. In addition, the ground truth segmentations are converted to the format used by the extended Berkeley Segmentation Benchmark for superpixel evaluation.
• collect_train_subset.m: A training subset comprising 200 images is depicted in list_train_subset.txt and this function is used to copy all files within this subset in separate folders.
• collect_test_subset.m: Copies all files belonging to a subset of the test set in separate folders.

Also consider the corresponding MatLab files for detailed instructions.
