Rectified Flowers

Rectified Flowers

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 one would see if one were doing panoramic imaging from inside a flower...

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

The flower rectification software 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.
