Color Transfer

Getting Started

The color_transfer.hpp header file is an OpenCV implementation based on Color Transfer between Images [Reinhard et al., 2001] and Adrian Rosebrock repository (for Python). The algorithm requires only the mean and standard deviation of pixel intensities for each channel in the Lab* color space.

This is an C++ approach from the above methods, for more information I recommend the above article or Adrian's post on his blog.

Requirements

• OpenCV
• boost/program_options*

*Optional - Used to get the input images from terminal

Installing

Just download this repository and use the header file color_transfer.hpp contained in the color_transfer folder.

Running the tests

A example is in sample folder. After compiling it, run the code below

$ ./color_transfer -s ../images/sunset.jpg -t ../images/ocean_day.jpg

$ ./color_transfer -s ../images/autumn.jpg -t ../images/woods.jpg

$ ./color_transfer -s ../images/old_pic.jpg -t ../images/city.jpg

$ ./color_transfer -s ../images/florest_day.jpg -t ../images/florest_dark.jpg
