1. A method for determining a density of particulate matter in a particulate filter sample, the method comprising:
generating, by a controller included in a computing system, a computed tomography (CT) scan-based image of the particulate filter sample;
segmenting, by the controller, the CT scan-based image of the particulate filter sample into a plurality of regions; and
for at least one region from the plurality of regions,
determining, by the controller, a density of a portion of the particulate filter sample corresponding to the at least one region of the CT scan-based image of the particulate filter sample by:
determining, by the controller, a grayscale value for the at least one region of the plurality of regions in the particulate filter;
determining, by the controller, a reference value for the at least one region based on a reference sample;
comparing, by the controller, the grayscale value to the reference value, wherein the reference value is correlated to a certain density level;
determining, by the controller, the density based on the comparison to the reference value which indicates the density level; and
causing, by the controller, an electronic display of a user device 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.
