Claim 10:
11. A non-transitory machine readable medium including instructions that, when executed by processing circuitry, cause the processing circuitry to perform operations comprising:
obtaining pixels from a camera system, the pixels of a scene observed by the camera system, the scene including a first repetitive feature and a second repetitive feature;
measuring, in a first group of pixels from the pixels, a first ratio of pixels corresponding to the first repetitive feature and pixels corresponding to the second repetitive feature;
measuring, in a second group of pixels from the pixels, a second ratio of the pixels corresponding to the first repetitive feature and the pixels corresponding to the second repetitive feature; and
determining a height difference between the first repetitive feature and the second repetitive feature based on a difference between the first ratio and the second ratio.
