Build

# For build you need custom opencv:
cd build
cmake -DCVPATH="YOUR_PATH_HERE/opencv/build" ..
make

Run Benchmark

./build/blend

Build requirements

1. cmake,
2. gcc
3. google-benchmark-devel
4. opencv
5. QT
6. Cuda toolkit (thrust lib)

TODO

1. Naive implementation using per pixel blending (with pointer magic??)
2. Multi thread implementation (openmp)
3. Thrust implementation https://stackoverflow.com/questions/22891244/blend-two-images-using-gpu

DONE

1. Opencv cuda

Notes

For fedora installation cuda toolkit use

cudo dnf config-manager --add-repo=https://negativo17.org/repos/fedora-nvidia.repo
sudo dnf install cuda-devel

Opecv Build

1. Build gcc 😄 🤬 💩

sudo dnf install gpm-devel mpfr-devel libmpc-devel libstdc++-devel glibc-devel

1. Clone opencv
2. Clone opencv-contrib

cd opencv
mkdir build
cd build

export CXX=/opt/gcc10.3.0/bin/g++

cmake -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH="../../opencv_contrib/modules" -DOPENCV_ENABLE_NONFREE=ON -DWITH_CUDA=ON  ..

# make sure cudaarithm in opencv modules in cmake output

make -j6
