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.

Delving into High-Quality Synthetic Face Occlusion Segmentation Datasets

The dataset is generated by two techniques, Naturalistic occlusion generation, Random occlusion generation. you must install face-occlusion-generation and dataset. see more guide in https://github.com/kennyvoo/face-occlusion-generation.git

Dataset Preparation

step 1

Create a folder for data generation materials on mmsegmentation folder.

mkdir data_materials

step 2

Please download the masks (11k-hands_mask.7z,CelebAMask-HQ-masks_corrected.7z) from this drive

Please download the images from CelebAMask-HQ, 11k Hands.zip and dtd-r1.0.1.tar.gz.

step 3

Download a upsampled COCO objects images and masks (coco_object.7z). files can be found in this drive.

Download CelebAMask-HQ and 11k Hands images split txt files. (11k_hands_sample.txt, CelebAMask-HQ-WO-train.txt) found in drive.

download file to ./data_materials
