Fast image convolution in C++

Includes handwritten CPU implementation using OpenMP, handwritten GPU implementation using CUDA, and implementations using some tools (like arrayFire)

Running

first, make sure you have conan installed (pip install conan)

mkdir build
cd build
conan install ..
cd ..
make

TODO:

• try to improve speedup on openGL implementation
• remove borders on image output
• write GPU code
• use CPU code to check GPU code for correctness
• write convolution with other frameworks and compare speed
  • HPX
  • ArrayFire?
  • C++20 coroutines
