Simple-does-it-weakly-supervised-instance-and-semantic-segmentation
There are five weakly supervised networks in Simple Does It: Weakly Supervised Instance and Semantic Segmentation, by Khoreva et al. (CVPR 2017). Respectively, Naive, Box, Box^i, Grabcut+, M∩G+. All of them use cheap-to-generate label, bounding box, during training and don't need other informations except image during testing.
This repo contains a TensorFlow implementation of Grabcut version of semantic segmentation.

Training (See Usage for more details)
Download pretrain vgg16
- tensorflow/models
- Put vgg_16.ckpt in 'models'
Extract annotations from 'Annotations' according to 'train.txt' or 'voc_train.txt' for VOC12 + SDB or VOC12
- For VOC12 + SBD (train set size: 10582)
- This will generate a 'train_pairs.txt' for 'grabcut.py'
python ./Dataset/make_train.py - For VOC12 (train set size: 1464)
- This will generate a 'voc_train_pairs.txt' for 'grabcut.py'
python ./Dataset/make_train.py --train_set_name voc_train.txt --train_pair_name voc_train_pairs.txt
Generate label for training by 'grabcut.py'
- Result of grabcut for each bounding box will be stored at 'Grabcut_inst'
- Result of grabcut for each image will be stored at 'Segmentation_label'
- Result of grabcut for each image combing with image and bounding box will be stored at 'Grabcut_pairs'
- Note: If the instance hasn't existed at 'Grabcut_inst', grabcut.py will grabcut that image
- For VOC12 + SBD (train set size: 10582)
python ./Preprocess/grabcut.py - For VOC12 (train set size: 1464)
python ./Preprocess/grabcut.py --train_pair_name voc_train_pairs.txt
Train network
- The event file for tensorboard will be stored at 'Logs'
- Train on VOC12 + SBD (train set size: 10582)
- This will consume lot of memory.
- The train set is so large.
- Data dtyp will be casted from np.uint8 to np.float16 for mean substraction.
- Eliminate mean substraction for lower memory usage.
- Change the dtype in ./Dataset/load.py from np.float16 to np.uint8
- Comment mean substraction in ./Model/model.py
python ./Model/model.py --is_train 1 --set_name train.txt - This will consume lot of memory.
- Train on VOC12 (train set size: 1464)
python ./Model/model.py --is_train 1 --set_name voc_train.txt
