Hmap

====



An image histogram remapping script written in Python 2.7 by [Anthony Kesich](http://kesi.ch) and [Ross Goodwin](http://rossgoodwin.com). Changes source image so that source image's histogram matches target image's histogram. Requires PIL/Pillow:



    $ sudo pip install Pillow



To run Hmap, cd into the directory where hmap.py (for black and white images) or hmap_c.py (for color images) is located. Ensure source and target images have the same height and width dimensions (in pixels), and place them in the directory. Run the script with 2 additional arguments (source and target image files) as shown in the following example.



Example:



    $ python hmap_c.py source_image.jpg target_image.jpg



hmap.py
