JColloids: Image analysis for video-microscopy studies of colloidal suspensions
We present an updated version of JChainsAnalyzer, a Java and ImageJ-based software for the analysis of video-microscopy images regarding the aggregation dynamics of super-paramagnetic particles in magneto-rheological fluids. This new version of the software has been adapted for a general use in image-based experiments of microprobes in suspension, and, consequently, has been renamed as JColloids. In this new version, the number of available options has been reduced, and the image filtering is virtually automatic, depending only on one numeric factor. JColloids has been recently used in the image analysis for micro-rheological studies using sedimented micro-particles in suspension and for tracking microbeads trapped by optical tweezers. The previous version of this program (AEDT_v1_0) may be found at http://dx.doi.org/10.1016/j.cpc.2009.04.016.
