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.

本研究推出了JChainsAnalyzer的更新版本——一款基于Java与ImageJ开发的软件，用于分析视频显微镜图像，以研究磁流变流体（magneto-rheological fluids）中超顺磁性粒子（super-paramagnetic particles）的聚集动力学过程。该新版本已适配悬浮态微探针（microprobes）基于图像的各类通用实验分析需求，因此更名为JColloids。在新版本中，可用配置项数量已精简，图像滤波（image filtering）环节已实现近乎全自动的处理流程，仅需调整一个数值参数即可完成。JColloids近期已被应用于两项研究的图像分析工作：一是利用悬浮态沉降微粒子开展的微流变学（micro-rheological）研究，二是对光镊（optical tweezers）捕获的微珠进行轨迹追踪的相关实验。
