Prepare datasets

It is recommended to symlink the dataset root to $MMSEGMENTATION/data. If your folder structure is different, you may need to change the corresponding paths in config files.

Cityscapes

The data could be found here after registration.

By convention, **labelTrainIds.png are used for cityscapes training. We provided a scripts based on cityscapesscripts to generate **labelTrainIds.png.

# --nproc means 8 process for conversion, which could be omitted as well.
python tools/convert_datasets/cityscapes.py data/cityscapes --nproc 8

Pascal VOC

Pascal VOC 2012 could be downloaded from here. Beside, most recent works on Pascal VOC dataset usually exploit extra augmentation data, which could be found here.

If you would like to use augmented VOC dataset, please run following command to convert augmentation annotations into proper format.

# --nproc means 8 process for conversion, which could be omitted as well.
python tools/convert_datasets/voc_aug.py data/VOCdevkit data/VOCdevkit/VOCaug --nproc 8

Please refer to concat dataset for details about how to concatenate them and train them together.

ADE20K

The training and validation set of ADE20K could be download from this link. We may also download test set from here.

Pascal Context

The training and validation set of Pascal Context could be download from here. You may also download test set from here after registration.

To split the training and validation set from original dataset, you may download trainval_merged.json from here.

If you would like to use Pascal Context dataset, please install Detail and then run the following command to convert annotations into proper format.

python tools/convert_datasets/pascal_context.py data/VOCdevkit data/VOCdevkit/VOC2010/trainval_merged.json

COCO Stuff 10k

The data could be downloaded here by wget.

For COCO Stuff 10k dataset, please run the following commands to download and convert the dataset.

# download
mkdir coco_stuff10k && cd coco_stuff10k
wget http://calvin.inf.ed.ac.uk/wp-content/uploads/data/cocostuffdataset/cocostuff-10k-v1.1.zip

# unzip
unzip cocostuff-10k-v1.1.zip

# --nproc means 8 process for conversion, which could be omitted as well.
python tools/convert_datasets/coco_stuff10k.py /path/to/coco_stuff10k --nproc 8

By convention, mask labels in /path/to/coco_stuff164k/annotations/*2014/*_labelTrainIds.png are used for COCO Stuff 10k training and testing.

COCO Stuff 164k

For COCO Stuff 164k dataset, please run the following commands to download and convert the augmented dataset.

# download
mkdir coco_stuff164k && cd coco_stuff164k
wget http://images.cocodataset.org/zips/train2017.zip
wget http://images.cocodataset.org/zips/val2017.zip
wget http://calvin.inf.ed.ac.uk/wp-content/uploads/data/cocostuffdataset/stuffthingmaps_trainval2017.zip

# unzip
unzip train2017.zip -d images/
unzip val2017.zip -d images/
unzip stuffthingmaps_trainval2017.zip -d annotations/

# --nproc means 8 process for conversion, which could be omitted as well.
python tools/convert_datasets/coco_stuff164k.py /path/to/coco_stuff164k --nproc 8
