This property only supports float value type precision; up to 5 decimal places (such as 0.00001) can typically be expected to be maintained. Further precision can be assigned but will be lost (truncated).
The bead coverage is a ratio of the number of bead pixels found at runtime to the average number of bead pixels found at train time. A "bead pixel" is any pixel between the two bead edges that has the same polarity (dark or light) as the bead itself. Often, all of the pixels between the two bead edges are bead pixels, but there can sometimes be holes in the bead.
The average number of bead pixels is computed at train time for each caliper. This value is computed by averaging the number of bead pixels from neighboring calipers. The number of calipers to average is specified by the SmoothingFactor train property.
