Classification: CPC A  G | IPC A

Claim 2:
3. The measurement system of claim 1, wherein:
the user-selected 2D endpoint is a pixel block including a first number of rows and a first number of columns; and
the at least one physical computing device identifies the matched 2D endpoint by:
identifying, within the second image, a rectangular area including a plurality of candidate pixel blocks each including the first number of rows and the first number of columns, the rectangular area including a second number of pixels rows greater than the first number of rows and a second number of columns greater than the first number of columns and at least two times greater than the second number of rows;
analyzing the candidate pixel blocks in the plurality of candidate pixel blocks included within the rectangular area to assign, to each of the candidate pixel blocks, a respective similarity metric with respect to the user-selected 2D endpoint; and
based on the analyzing, identifying as the matched 2D endpoint corresponding to the feature a particular candidate pixel block that is assigned a highest similarity metric of the respective similarity metrics assigned to the analyzed candidate pixel blocks in the plurality of candidate pixel blocks.
