The procedure, shown diagrammatically in Figure 1, is to first identify edges in the image area and draw profiles of predetermined length perpendicular to these. In the software version used for this study profiles with insufficient contrast are rejected (shown in red in Figure 1). The average of the slope parameters of an error function fitted through each of the identified profiles gives the sharpness value, s for the image.
