Introduction

We provide the code for reproducing experiment results of SCNet.

Dataset

SCNet requires COCO and COCO-stuff dataset for training. You need to download and extract it in the COCO dataset path. The directory should be like this.

Results and Models

The results on COCO 2017val are shown in the below table. (results on test-dev are usually slightly higher than val)

Notes

• Training hyper-parameters are identical to those of HTC.
• TTA means Test Time Augmentation, which applies horizonal flip and multi-scale testing. Refer to config.
