Introduction

The repository contains the preprocessing code of the Cityscapes dataset for CASENet. CASENet is a recently proposed deep network with state of the art performance on category-aware semantic edge detection. For more information about CASENet, please refer to the arXiv paper and the paper published in CVPR 2017.

Usage

Note: In this part, we assume you are in the directory $CITYSCAPES_PREPROCESS_ROOT/

1. Download the files "gtFine_trainvaltest.zip" and "leftImg8bit_trainvaltest.zip" from the Cityscapes website to data_orig/, and unzip them.

   unzip data_orig/gtFine_trainvaltest.zip && rm data_orig/gtFine_trainvaltest.zip
   unzip data_orig/leftImg8bit_trainvaltest.zip && rm data_orig/leftImg8bit_trainvaltest.zip
   

2. Run the matlab code to preprocess the data.

   # In Matlab Command Window
   run code/demo_preproc.m
   

   This will generate the .bin edge labels and the corresponding file lists that could be read by CASENet in data_proc/.
