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

# Pick your mirror:
wget http://mirror.linux-ia64.org/gnu/gcc/releases/gcc-10.3.0/gcc-10.3.0.tar.xz

tar -xf gcc-10.3.0.tar.xz
cd gcc-10.3.0
