Download

git clone --recursive git@github.com:wavelab/GTA-Cuda-Remapping.git

Build

cd GTA-Cuda-Remapping
mkdir build
cd build
cmake ..
make

Run

./Remapping -i <input_folder> -n <num_threads> -o <output_path> -m <map_file>

This will recursively search in input_folder for anything that has "png" extension. It will output in <output_path> with the same file name and folder structure.

Map Files

See the examples folder for examples of useful map files. Every line in the map file must be formatted as follows:

<old_r> <old_g> <old_b> <new_r> <new_b> <new_g>

This program will find all values in each image with the old_{r,g,b} and replace it with new_{r,g,b} respectively. Values that are not found in the map file are set to (0,0,0).

Requirements

• OpenCV
• Cuda 8+ (nvcc in path)

Notes

This is very specific for our purpose of remapping our colours (after post processing) to cityscapes, not much is done for extendability.
