BackRazor For Segmentation

Environment Setting

1. Install the packages required by backRazor
2. Install packages

pip install visdom matplotlib

# install actnn
git clone git@github.com:ucbrise/actnn.git
cd actnn/actnn
pip install -v -e .

3. Prepare datasets

• Standard Pascal VOC You can run train.py with "--download" option to download and extract pascal voc dataset. The defaut path is './datasets/data':

/datasets
    /data
        /VOCdevkit 
            /VOC2012 
                /SegmentationClass
                /JPEGImages
                ...
            ...
        /VOCtrainval_11-May-2012.tar
        ...

• Pascal VOC trainaug: ./datasets/data/train_aug.txt includes the file names of 10582 trainaug images (val images are excluded). Please to download their labels from Dropbox or Tencent Weiyun. Those labels come from DrSleep's repo.

Extract trainaug labels (SegmentationClassAug) to the VOC2012 directory.

/datasets
    /data
        /VOCdevkit  
            /VOC2012
                /SegmentationClass
                /SegmentationClassAug  # <= the trainaug labels
                /JPEGImages
                ...
            ...
        /VOCtrainval_11-May-2012.tar
        ...
