Table 3.

We recorded a total of 12 panoramic images and divided them into two groups; one group where direct sunlight is shining onto the sensor (e.g., Figure 15 and Figure 16) and one where the Sun is covered by clouds. The classification rates for the separation techniques tested on each panoramic image, as well as the average classification rate for each group is shown; the column representing the results for the skyline shown in Figure 17 is highlighted (bold).
