Table 4.
Statistical parameters of the mismatch error as the distance from the reference camera varies.

For each distance from the reference camera, the average value as a percentage of the homographed image side and the error standard deviation are reported. Values are given for each pair of cameras, 1-2, 1–3, and 2-3, and finally as an average of the three camera pairs.
