Threshold # get and set (DirectionEdgeStatisticalCommand)
Threshold value used to determine which pixels are edge pixels. If the difference in the intensity value between the pixel being tested and the average intensity of the pixels in the area specified in the Dimension property around it is greater than this value, the pixel is an edge pixel. The threshold range for the 16, 48, and 64-bit images is from 0 to 65535 and for 12-bit images from 0 to 4095. Otherwise, it is from 0 to 255. The threshold is applied on channels separately.
