A thickness of a first layer in a structure may be measured based on an original image of the structure. A first boundary of the first layer may be identified in the original image. A second boundary that is substantially indistinguishable in the original image may be identified based on converting the original image into a first image based on the first boundary and generating a second image based on filtering the first image. The first image may be generated based on adjusting partial image portions of the original image to align the representation of the first boundary with an axis line, such that the first image includes a representation of the first boundary that extends substantially in parallel with the axis line. The second boundary may be identified from the second image, and the thickness of the layer may be determined based on the identified first and second boundaries.
