X-ray computed tomography case study: Triangle and pentagon datasets with various sizes, scales, and noise levels

The dataset consists of two laser-cut objects made from a 6-mm-thick transparent plastic material called acrylate. The objects have triangular and pentagonal shapes, each containing 12 samples with varying sizes. The right-angle edges of the triangular samples range from 2.8 cm to 4.0 cm, while the edges of the pentagonal samples range from 2.5 cm to 3.0 cm. Each scanning session involved different placements of the objects, resulting in variations in rotation and translation.
