To run the code:

• GCC 6 or higher
• OpenCV 3.4 (You need use git checkout 3.4 to specify this version when install from OpenCV source code)
• pkg-config

To install OpenCV in Ubuntu (For Windows users, you need to use WSL)

Step 1: Update the Ubuntu system packages

sudo apt-get update && sudo apt-get upgrade

Step 2: Install required tools and packages

sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

Step 3: Download OpenCV sources using git

sudo -s

cd /opt

git clone https://github.com/Itseez/opencv.git

git clone https://github.com/Itseez/opencv_contrib.git

Step 4: Checkout branch 3.4 in opencv and opencv_contrib

cd opencv_contrib

git checkout 3.4

cd ..

cd opencv

git checkout 3.4

Step 5: Build and Install OpenCV

mkdir release

cd release

cmake -D BUILD_TIFF=ON -D WITH_CUDA=OFF -D ENABLE_AVX=OFF -D WITH_OPENGL=OFF -D WITH_OPENCL=OFF -D WITH_IPP=OFF -D WITH_TBB=ON -D BUILD_TBB=ON -D WITH_EIGEN=OFF -D WITH_V4L=OFF -D WITH_VTK=OFF -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D OPENCV_GENERATE_PKGCONFIG=ON -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/opt/opencv_contrib/modules /opt/opencv/

make -j4

make install

ldconfig

exit

cd ~

Step 6: Find and Set "opencv.pc" file path

ls /usr/local/lib/pkgconfig/

sudo cp /usr/local/lib/pkgconfig/opencv.pc /usr/lib/x86_64-linux-gnu/pkgconfig/opencv.pc

Step 7: Check OpenCV version

pkg-config --modversion opencv

If the output is "3.4.x", you are good to go.

Compile

You need to open terminal and compile code. Read readme.md in each folder for more information.

Version

Compile the Code

Compile on Ubuntu:

g++ -std=c++11 -fpermissive -o test main.cpp fasthessian.cpp integral.cpp ipoint.cpp surf.cpp utils.cpp `pkg-config opencv --cflags --libs`

GCC Optimize

g++ -std=c++11 -fpermissive -Ofast -o test main.cpp fasthessian.cpp integral.cpp ipoint.cpp surf.cpp utils.cpp `pkg-config opencv --cflags --libs`

To run parallel with openmp

g++ -fopenmp -std=c++11 -fpermissive -Ofast -o test main.cpp fasthessian.cpp integral.cpp ipoint.cpp surf.cpp utils.cpp `pkg-config opencv --cflags --libs`

Run the Code

./test -m <mode> [...]

Argument Options (< > after flag indicates argument is required)

• -m | --mode < >:

  • 1: run static image match between a pair of images
    • 2: run image stitching with local video files

• -b | --blend_mode: (no additional argument)

  • if set, run blending algorithm with stitching; otherwise, run regular stitching algorithm

• -L/R | --src1/src2

  --src1/src2 is the path to images or videos file

For example: ./test -m 1 -L ./image/1.jpg -R ./image/2.jpg
