New Samoa Coral Mapping results with Fluid Lensing

April 2, 2014 - Updated fluid lensing results from the Reactive Reefs project in American Samoa.

These are the first data sets processed on the new computer setup (funded by you!) and Agisoft's generous donation of their professional GIS software.

Hover over figures to see descriptions below:

Fluid lensing on aerial Samoa DataRAW aerial image on the right and 45-frames (0.75 seconds of video data) post processed using Fluid Lensing on the left. Notice under sampled original image with compression artifacts, caustics and wave distortions renders nearly all structure indistinguishable. Lensed data show clear features and no caustics. Fluid lensing removes surface distortions that typically limit 3D reconstruction ability. Below, I show the fluid lensing enabled 3D reconstruction using structure from motion for a segment of flight data. Note boundary regions show errors due to insufficient data and overlap in those regions, but the full data set will merge all flights for sufficient overlap. Data are rendered at 1/10th actual resolution.
