A robust nucleation tracking technology was proposed to track the nucleation process of l-glutamic acid in this study. A motion-based multiple object tracking (MMOT) model was introduced to crystallization, for the first time, to help to track the moving crystals. A waterproof microcamera combined with a home-designed vial adaptor was used to record the nucleation process video stream. Optimization of parameters in the MMOT model and a moving average (MA) based smoothing method helped to determine the starting point of nucleation. Results showed the newly developed technology performed better under the influence of ultrasonic irradiation, which disabled the use of focused beam reflection measurement (FBRM).

超声诱导形核的基于运动的多目标跟踪：以l-谷氨酸为例

在这项研究中，提出了一种鲁棒的成核追踪技术来追踪1-谷氨酸的成核过程。首次将基于运动的多对象跟踪（MMOT）模型引入结晶，以帮助跟踪移动的晶体。防水微型相机与家庭设计的样品瓶适配器结合在一起，用于记录成核过程视频流。MMOT模型中参数的优化和基于移动平均（MA）的平滑方法有助于确定成核的起点。结果表明，新开发的技术在超声辐射的影响下表现更好，这使聚焦光束反射测量（FBRM）的使用无法使用。
