Figure 6. Mean error and standard
deviation (error bar) distribution for
the image pairs processed by
LDOF

Figure 7. The top frames in (a) and (b) show the image pairs selected to compute the LDOF, and below left the estimated flow
field with greyscale-coding for a better visualization; the error reconstruction are shown, respectively. Note that (a) represents
a significantly changing lighting condition resulting in poor estimation of the glacier motion, while (b) illustrates good
lighting conditions, and although the glacier has a large displacement, yet it is correctly matched.
