## README
**Deformable ConvNets** is initially described in an [arxiv tech report](https://arxiv.org/abs/1703.06211).
**R-FCN** is initially described in a [NIPS 2016 paper](https://arxiv.org/abs/1605.06409).
**Soft-NMS** is initially described in an [arxiv tech report](https://arxiv.org/abs/1704.04503).
Our goal was to test Soft-NMS with a state-of-the-art detector, so Deformable-R-FCN was trained on 800x1200 size images with 15 anchors. Multi-Scale testing was also added with 6 scales. Union of all boxes at each scale was computed before performing NMS. Please note that the repository does not include the scripts for multi-scale testing as I just cache the boxes for each different scale and do NMS separately. The scales used in multi-scale testing were as follows, [(480, 800), (576,900), (688, 1100), (800,1200), (1200, 1600), (1400, 2000)].
