DSRL: Dual Super-Resolution Learning for Semantic Segmentation

The code is inspired by EdgeNet in pytorch, you can follow the procedure in it to prepare the datasets and model directory files.

Unzip the repo folder

# first download and unzip the repo folder
unzip dsrl_released-master.zip
cd dsrl_released-master

Testing

• The first step aims to save the gray prediction mask
• The second step aims to evaluate the mIoU with prediction mask and groundtruth

# To evaluate ESPNetv2_DSRL, use below command:
sh run_eval_256x512.sh   
# sh run_eval_512x1024.sh

Main results
