“…In the future we propose to compute the disparity using the points where a normal from the image origin intersects the given line. These measured points can then be used in a Kalman Filter based algorithm such as [13,14], to estimate range to that particular feature point.…”

“…Figure 4 shows two line segments that might be considered for linking. The decision to link the two segments is based on the following inequalities: d1+d4-2d3>O (14) d2>d1-i-d4-2d3 (15) The first condition in eq. 14 insures that the lines are not overlapped, overlapped lines will not be linked since, most likely, they are not part of the same edge.…”

“…As an example, the raw GHI obtained on June 4, 2011, is shown in Figure 1.14(b). The GHI recorded every second is normalized with respect to the clear-sky GHI obtained from the NSRDB database at a nearby location [41]. The maximum spatial separation among sensors is 0.7 mile, resulting in the minimum spatial correlation coefficient of 0.5.…”

“…In feature based methods (Sridhar B. et al, 1993), significant features are detected from the images and matching between features are made from frame to frame using normalized correlation. But since only features are used, the choice of the feature set becomes very critical for the success of the method.…”
