Salient Frame Detection for Molecular Dynamics Simulations

Saliency-based analysis can be applied to time-varying 3D datasetsfor the purpose of summarization, abstraction, and motion analysis. As the sizes
of time-varying datasets continue to grow, it becomes more and more difficult to
comprehend vast amounts of data and information in a short period of time. Au-
tomatically generated thumbnail images and previewing of time-varying datasets
can help viewers explore and understand the datasets significantly faster as well
as provide new insights. In this paper, we introduce a novel method for detect-
ing salient frames for molecular dynamics simulations. Our method effectively
detects crucial transitions in simulated mechanosensitive ion channel (MscS), in
agreement with experimental data.
