Identified Fibers and Validation Data for Fiber Identification

The following data sets belong to the µCT scan of a nonwoven sample provided by Reifenhäuser Reicofil GmbH & Co. KG.

Aside from the actual scan, in the first data set, we provide a segmentation of the scan into pore space and fibers.

In addition, we supply another virtual 3D scan in which the individual fibers are identified as separate objects. This identification was carried out using a Neural Network validated with artificial data, which make up the second data set.

The methodology is part of the doctoral thesis of Andreas Griesser and it is described in more detail in an upcoming article. The size of the nonwoven sample scan and the virtual scan with the identified fibers is 15,363 x 3,960 x 2,112 voxels each. The ultra-large size is intended and suitable as a benchmark for real nonwovens and high-performance algorithms.

The data has been used by Reifenhäuser Reicofil GmbH & Co. KG in their Patent No. WO 2020/103964 A1. The algorithms were thereby required for the proof of patentability of the nonwoven.
