Abstract: We present a tool which supports CT specialists in exploring the parameter and result space of volume segmentation pipelines. In a preprocessing step, the user samples the parameter space of a number of pipelines to be analysed. Our sampling tool supports arbitrary pipeliness that can be parametrized via the command line. The user can then explore the space of possible results of the sampled pipelines in an interactive visualization tool. This visualization tool highlights the variation resulting from different parametrizations and pipelines, and allows exploring the influence of each parameter. We evaluate our tool on the multimodal segmentation of a carbon-fiber-reinforced polymer (CFRP) specimen with impact damage, scanned with a Talbot-Lau Grating Interferometer Computed Tomography device.

Keywords: image processing (264), segmentation (19), visualization (88), Computed Tomography (283), parameter space exploration (1), multimodal segmentation (1),
