A method for measuring a dimension of a device includes receiving an image of a portion of the device, receiving a first offset value and a second offset value, processing the image to define a least one graph of a line of pixels, the at least one graph including the brightness level of each pixel in a line of pixels, identifying a location of a first peak and a second peak in the graph, defining a first exclusion area boundary, defining a second exclusion area boundary, setting the brightness level of the pixels between the first exclusion area boundary and the second exclusion area boundary to zero, identifying a first portion of the feature of interest and a second portion of the feature of interest, and measuring a distance between the first portion of the feature of interest and the second portion of the feature of interest.
