a Example of a plot of detected x-coordinates of the object centre for valid segments (black line), plotted over slice position, for a sediment core. The blue line indicating core position in x was fit to the largest segment (grey area). b Example axial CT image of the phantom used for evaluation of the algorithm, showing the placement of regions of interest (ROIs) in the low-contrast section of the phantom
