HDR+ Implementation

Original Document on the subject (by Timothy Brooks): https://timothybrooks.com/tech/hdr-plus

Currently maintained by Simon Gardling

Compilation instructions:

  1. Install the Nix package manager
  2. Run the below commands:
nix-shell -I shell.nix # enter a development environment
mkdir build
cd build
cmake ..
make -j`nproc`

HDR+ algorithm examples:

There are three zip files with examples of the HDR+ algorithm at: https://www.gardling.com/hdr_plus

Compiled Binary Usage:

Usage: ./hdrplus [-c comp -g gain (optional)] dir_path out_img raw_img1 raw_img2 [...]

The -c and -g flags change the amount of dynamic range compression and gain respectively. Although they are optional because they both have default values.
