Automatically stiching several individual images to generate a panorama image. Follow the routine described in the paper Automatic Panoramic Image Stitching using Invariant Features. For more details about theory and practice of panorama image stitching including algorithms, results and analysis, please read my post. Any feedback is welcomed!

Implement with The CImg Library and VLFeat open source library in C++ language.

Test on Visual Studio 2015, C++11. You can also compile in Linux with linuxbuild.sh.

Images should be of bmp format(much easier to convert by ImageMagick).

Download and unpack the latest VLFeat binary distribution (I used VLFeat 0.9.20 binary package on May 11, 2017) in a directory of your choice (e.g. F:\vlfeat-0.9.20-bin) For Mac users, read this Apple X-Code tutorial. These instructions show how to setup a basic VLFeat project with Visual Studio 2015 on Windows 10 (64 bit). Instructions for other versions of Visual Studio and Windows should be similar.

1. Specify the value of the PATH environment variable. E.g. Add F:\vlfeat-0.9.20-bin\vlfeat-0.9.20\bin\win64 to Path, where win64 depends on your architecture.
2. Open VS and select File > New > Project and choose General > Empty Project.
3. Click Project > Properties to open Property Pages. Choose Configuration > All Configurations.
4. Select Configuration Properties > C/C++ > General and add the root path of the VLFeat folder (e.g. F:\vlfeat-0.9.20-bin\vlfeat-0.9.20) to Additional Include Directories.
5. Select Configuration Properties > Linker > General and add the bin/win32 folder (even if your architecture is win64) (e.g. F:\vlfeat-0.9.20-bin\vlfeat-0.9.20\bin\win32) to Additional Library Directories.
6. Select Configuration Properties > Linker > Input and add vl.lib to Additional Dependencies.
7. Copy the vl.dll file in bin/win32 folder (e.g. F:\vlfeat-0.9.20-bin\vlfeat-0.9.20\bin\win32) to your VS project's debug or release folder (e.g. C:\Users\HYPJUDY\Documents\Visual Studio 2015\Projects\PanoramaImageStitching\Debug).
8. Build and run the project (Ctrl+F5)
