Pendent drop profile integration and fitting
This plug-in allows for interactive or automated adjustment of a profile to an image of a pendent drop. The surface tension, volume and surface associated with this profile can then be obtained.
The pendent drop method is commonly used to measure surface tensions of liquids. It consists in analysing the shape of a drop hanging typically from a capillary tube and about to detach (sometimes the inverse situation of a bubble forming at the bottom of a liquid is preferred, or that of a sessile drop or bubble). The shape is very sensitive to the unknown interfacial tension. The drop profile is described by only one non-dimensional parameter (tip radius over capillary length), although in practice five dimensional parameters can be adjusted within this plug-in: tip position and curvature, tilt of symetry axis and capillary length. The surface tension is calculated from the latter if the density difference is given.
For more information see the included PDF documentation (Plugins -> Drop Analysis -> About Pendent Drop, or in the article directory of the source code) or the open access publication

The latest stable version is uploaded to the Fiji update site http://sites.imagej.net/Daerr/
Follow the procedure described on the Fiji wiki at http://fiji.sc/How_to_follow_a_3rd_party_update_site to add that site to Fiji's list and install the plugin.
I do not recommend using the git version, simply because it may be in an unusable state for long periods during rewrites. If you nevertheless insist on trying the latest version under development, check the commit history and use either maven or fiji+jar to compile and package the plugin for you.
