Rectified Flowers

29 June 2010 / code, project

Kyle McDonald and I were reading about domain shifting between polar and Cartesian geometries, and noticed that flowers make particularly interesting subjects for this transformation. Abusing my open-source BloggieUnwarper panoramic-imaging software with some flower photographs from Flickr, we produced the “flower panoramas” below. This is what you would see if you were doing panoramic imaging from inside a flower

A complete set of about two dozen such panoramas can be seen in this Flickr set.

A modified version of the software — the FlowerUnwarper — was optimized for unwarping flower images, and is available here (including source code). The software is built in Processing and uses the ControlP5 library. All of the source photos used in this project were distributed with Creative Commons Attribution licenses. Our software is free in the Public Domain and our own re-processed images are released under the Creative Commons Attribution-ShareAlike 3.0 Unported License.

Update (July 10): The folks at NotCot have since used our software to create these fascinating views of unwarped chandeliers!

Keywords: polar to cartesian, flowers, warping, unwarping, unwrapping, dewarping, rectification, inverse warping, correction, panorama, macro, macrophotography, Processing, surrealism, flower landscapes, petals, Processing, Java, free source code, free software, polar transformation of flowers.

    These are beautiful! Thanks for sharing the Processing sketch, too. I’ve done something similar with a series of pics I call ‘Unwound’. I think I even have one on my HD from the same passion flower image. :)
