Repulsion Loss: Detecting Pedestrians in a Crowd. https://arxiv.org/abs/1711.07752
Forked from PyTorch-SSD, which is a PyTorch implementation of Single Shot MultiBox Detector from the 2016 paper by Wei Liu, Dragomir Anguelov, Dumitru Erhan, Christian Szegedy, Scott Reed, Cheng-Yang, and Alexander C. Berg. The official and original Caffe code can be found here.
Shell # First install Python server and client pip install visdom # Start the server (probably in a screen or tmux) python -m visdom.server
To make things easy, we provide bash scripts to handle the dataset downloads and setup for you. We also provide simple dataset loaders that inherit
torch.utils.data.Dataset, making them fully compatible with the
Microsoft COCO: Common Objects in Context
# specify a directory for dataset to be downloaded into, else default is ~/data/ sh data/scripts/COCO2014.sh
PASCAL VOC: Visual Object Classes
# specify a directory for dataset to be downloaded into, else default is ~/data/ sh data/scripts/VOC2007.sh #
# specify a directory for dataset to be downloaded into, else default is ~/data/ sh data/scripts/VOC2012.sh #

To evaluate a trained network:
You can specify the parameters listed in the
eval.pyfile by flagging them or manually changing them.

# make sure pip is upgraded pip3 install --upgrade pip # install jupyter notebook pip install jupyter # Run this inside ssd.pytorch jupyter notebook

We have accumulated the following to-do list, which we hope to complete in the near future - Still to come: * [x] Support for the MS COCO dataset * [ ] Support for SSD512 training and testing * [ ] Support for training on custom datasets * [ ] Support for RepBox term * [ ] Support for selecting the second largest IoU from the same class
