We designed and developed an interactive visualization approach for exploring and comparing image sequences in the context of porous media research. Our tool facilitates the visual analysis of two-dimensional image sequence datasets captured during fluid displacement experiments in a porous micromodel. The images are aggregated into a single graph-based representation, allowing for an experiment to be visualized across its entire temporal domain. This graph is generated from the viscous flow patterns of the invading fluid, reducing the need for manual image masking and clean-up steps. The Node-Link representation of the graph is superimposed onto the raw images, creating a composite spatio-temporal view of the dataset. We demonstrate the functionality of our implementation by evaluating its output and performance on a collection of related datasets. We found that separate experiments in the same porous medium yield topologically different, yet visually similar flow graphs with comparable node positions.
