- Go to: NVIDIA cuDNN home page: https://developer.nvidia.com/cudnn.
- Click Download.
- Complete the short survey and click Submit.
- Accept the Terms and Conditions. A list of available download versions of cuDNN displays.
- Select the cuDNN version that you want to install. A list of available resources displays.
Before issuing the following commands, you must replace X.Y and 8.x.x.x with your specific CUDA and cuDNN versions. Navigate to your directory containing the cuDNN Debian local installer file.
```
$ sudo dpkg -i cudnn-local-repo-${OS}-8.x.x.x_1.0-1_amd64.deb
```

Import the CUDA GPG key.

Install the code samples and the cuDNN library documentation.
```
$ sudo apt-get install libcudnn8-samples=8.x.x.x-1+cudaX.Y
```

2.0. Compile and install OpenCV with Cuda and cuDNN

We will now proceed with the installation (see the Qt flag that is disabled to do not have conflicts with Qt5.0).

$ cd ~/Downloads
$ wget -O opencv.zip https://github.com/opencv/opencv/archive/refs/tags/4.6.0.zip
$ wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/refs/tags/4.6.0.zip
$ unzip opencv.zip
$ unzip opencv_contrib.zip

Create a virtual environtment for the python binding module (OPTIONAL)

$ sudo pip install virtualenv virtualenvwrapper
$ sudo rm -rf ~/.cache/pip

Edit ~/.bashrc

$ export WORKON_HOME=$HOME/.virtualenvs
$ export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
$ source /usr/local/bin/virtualenvwrapper.sh
$ mkvirtualenv cv -p python3
$ pip install numpy

Procced with the installation

$ cd opencv-4.6.0
$ mkdir build
$ cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D WITH_TBB=ON \
-D ENABLE_FAST_MATH=1 \
-D CUDA_FAST_MATH=1 \
-D WITH_CUBLAS=1 \
-D WITH_CUDA=ON \
-D BUILD_opencv_cudacodec=OFF \
-D WITH_CUDNN=ON \
-D OPENCV_DNN_CUDA=ON \
-D CUDA_ARCH_BIN=6.1 \
-D WITH_V4L=ON \
-D WITH_QT=OFF \
-D WITH_OPENGL=ON \
-D WITH_GSTREAMER=ON \
-D OPENCV_GENERATE_PKGCONFIG=ON \
-D OPENCV_PC_FILE_NAME=opencv.pc \
-D OPENCV_ENABLE_NONFREE=ON \
-D OPENCV_PYTHON3_INSTALL_PATH=~/.virtualenvs/cv/lib/python3.10/site-packages \
-D PYTHON_EXECUTABLE=~/.virtualenvs/cv/bin/python \
-D OPENCV_EXTRA_MODULES_PATH=~/Downloads/opencv_contrib-4.6.0/modules \
-D INSTALL_PYTHON_EXAMPLES=OFF \
-D INSTALL_C_EXAMPLES=OFF \
-D BUILD_EXAMPLES=OFF ..

To use CUDNN you must modify those flags (to set the correct value of CUDA_ARCH_BIN you must visit https://developer.nvidia.com/cuda-gpus and find the Compute Capability CC of your graphic card). Then write the correct version in CUDA_ARCH_BIN. For example: for the GTX 1060 it would be 6.1
```
    ...
    -D WITH_CUDNN=ON \
    -D OPENCV_DNN_CUDA=ON \
    -D CUDA_ARCH_BIN=6.1 \
    ...
```

Before the compilation you must check that CUDA has been enabled in the configuration summary printed on the screen. (If you have problems with the CUDA Architecture go to the end of the document).

...
--   NVIDIA CUDA:                   YES (ver 11.7, CUFFT CUBLAS FAST_MATH)
--     NVIDIA GPU arch:             75
--     NVIDIA PTX archs:
-- 
--   cuDNN:                         YES (ver 8.5.0)
...

If it is fine proceed with the compilation (Use nproc to know the number of cpu cores):
```
 $ nproc
 $ make -j8
 $ sudo make install
```

Include the libs in your environment

$ sudo /bin/bash -c 'echo "/usr/local/lib" >> /etc/ld.so.conf.d/opencv.conf'
$ sudo ldconfig

If you want to have available opencv python bindings in the system environment you should copy the created folder during the installation of OpenCV (* -D OPENCV_PYTHON3_INSTALL_PATH=~/.virtualenvs/cv/lib/python3.10/site-packages *) into the dist-packages folder of the target python interpreter:
```
$ sudo cp -r ~/.virtualenvs/cv/lib/python3.10/site-packages/cv2 /usr/local/lib/python3.10/dist-packages
```
- Modify config-3.10.py to point to the target directory"
```
$ sudo nano /usr/local/lib/python3.10/dist-packages/cv2/config-3.10.py 
```
```
PYTHON_EXTENSIONS_PATHS = [
    os.path.join('/usr/local/lib/python3.10/dist-packages/cv2', 'python-3.10')
] + PYTHON_EXTENSIONS_PATHS
```

3.0 EXAMPLE TO TEST OPENCV 4.5.2 with GPU in C++

Verify the installation by compiling and executing the following example:

#include <iostream>
#include <ctime>
#include <cmath>
#include "bits/time.h"

#include <opencv2/core.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/imgproc.hpp>
#include <opencv2/imgcodecs.hpp>

#include <opencv2/core/cuda.hpp>
#include <opencv2/cudaarithm.hpp>
#include <opencv2/cudaimgproc.hpp>

#define TestCUDA true

int main() {
    try {
        cv::String filename = "picture.jpg";
        cv::Mat srcHost = cv::imread(filename, cv::IMREAD_GRAYSCALE);

        std::clock_t cpu_begin = std::clock();
        for(int i=0; i<1000; i++) {
            cv::Mat dst;
            cv::bilateralFilter(srcHost,dst,3,1,1);
        }
        std::clock_t cpu_end = std::clock();

        std::clock_t gpu_begin = std::clock();
        for(int i=0; i<1000; i++) {
            cv::cuda::GpuMat dst, src;
            src.upload(srcHost);

            //cv::cuda::threshold(src,dst,128.0,255.0, CV_THRESH_BINARY);
            cv::cuda::bilateralFilter(src,dst,3,1,1);

            cv::Mat resultHost;
            dst.download(resultHost);
        }
        std::clock_t gpu_end = std::clock();

        //cv::imshow("Result",resultHost);
        //cv::waitKey();

        std::cout << "CPU: " << double(cpu_end-cpu_begin) / CLOCKS_PER_SEC  << std::endl;
        std::cout << "GPU: " << double(gpu_end-gpu_begin) / CLOCKS_PER_SEC  << std::endl;

    } catch(const cv::Exception& ex) {
        std::cout << "Error: " << ex.what() << std::endl;
    }
}

$ g++ test.cpp `pkg-config opencv --cflags --libs` -o test
$ ./test`
