This is an Implementation of Fast Single-Image Haze Removal Algorithm Using Color Attenuation Prior [1], done as a term project for an image processing class. It also includes an implementation of Guided Image Filtering [2].
Implemented in C++14, using DevIL for loading and saving images.

CMake is used to generate builds.
Install DevIL from your package manager, e.g. for Debian-based distros:
$ sudo apt-get install libdevil-dev
Then create a build directory, navigate to it, and invoke CMake:
$ cmake <haze-removal-root-dir>
Build using make:
$ make -j4
CMake's find_package(DevIL) seems to have some problems on Windows. A working approach is to manually specify include directory and library files:
Download the DevIL Windows SDK from e.g. the DevIL sourceforge page.
Extract to some directory, e.g. C:\lib\.
Create a build directory, navigate to it, then invoke CMake:
$ cmake <haze-removal-root-dir> -DIL_INCLUDE_DIR="C:\lib\DevIL Windows SDK\include" -DIL_LIBRARIES="C:\lib\DevIL Windows SDK\lib\x86\Release\DevIL.lib" -DILU_LIBRARIES="C:\lib\DevIL Windows SDK\lib\x86\Release\ILU.lib"
Replace C:\lib\ with wherever you extracted the DevIL SDK, replace x86 with x64 if you are doing a 64-bit build.
CMake will then produce a Visual Studio solution.
The DLL files provided with the SDK need to be either copied into the same directory as the resulting .exe file, or into a directory in the PATH environment variable.
