Claim 13:
14. A non-transitory computer-readable media comprising instructions stored thereon that, when executed by a processor of a computer system, cause the computer system to perform operations to determine a density of particulate matter in a diesel particulate filter (DPF) sample, the operations comprising:
generating a computed tomography (CT) scan-based image of the DPF sample;
segmenting the CT scan-based image of the DPF sample into a plurality of regions; and
for at least one region from the plurality of regions,
determining a density of a portion of the DPF sample corresponding to the at least one region of the CT scan-based image of the DPF sample by:
determining a grayscale value for the at least one region of the plurality of regions in the particulate filter;
determining a reference value for the at least one region based on a reference sample;
comparing the grayscale value to the reference value, wherein the reference value is correlated to a certain density level; and
determining the density based on the comparison to the reference value which indicates the density level; and

causing an electronic display of a user device communicatively coupled to the computer system to display the CT scan-based image comprising the at least one region and an indication of the density for the at least one region.
