color_transfer package is an OpenCV and Python implementation based (loosely) on Color Transfer between Images [Reinhard et al., 2001] The algorithm itself is extremely efficient (much faster than histogram based methods), requiring only the mean and standard deviation of pixel intensities for each channel in the L*a*b* color space.
For more information, along with a detailed code review, take a look at this post on my blog.
#Install To install, make sure you have installed NumPy and compiled OpenCV with Python bindings enabled.
From there, there easiest way to install is via pip:
$ pip install color_transfer
Below are some examples showing how to run the
example.py demo and the associated color transfers between images.
$ python example.py --source images/autumn.jpg --target images/fallingwater.jpg
$ python example.py --source images/woods.jpg --target images/storm.jpg
$ python example.py --source images/ocean_sunset.jpg --target images/ocean_day.jpg
