py-popsift

this is a python binding of popsift(a open-source implementation of the sift algorithm in CUDA) , you can use it in python-opencv . It usually speed up 15X then cpu .

test environment

• cuda 10.2
• gcc 8.3.1
• python 3.7.6
• pybind11 2.6.1
• opencv 4.5.0

py-popsift's Issues

Getting pybind11

Perhaps you should mention, that pybind11 should be available, e.g. by installing as submodule:
git submodule add https://github.com/pybind/pybind11.git
In my case, I also had to adjust the path to pybind11 in the CMakeLists.txt file.
Also, instructions like
mkdir build && cd buld
make -j4
will be helpful for some others.

After that, it was working, but on a NVidia Jetson Orin NX the speed advantage compared to the CPU version of OpenCV SIFT was not very big.
