above the width threshold, the resulting laser line width is 0. In this case the width
threshold value should be changed.
Laser line height For the COG algorithm, the laser line height is the highest grey value of the
detected laser line. In order to suppress noise, the laser line height of the LineFinder
algorithm is the mean value between the two pixels surrounding the peak position.
Depending on the shape of the peak, this may not result in the maximum peak value.
The value of the threshold should be set slightly above the grey level of the im-
age background. The width threshold value should be set so that the maximum
peak width of 63 is not exceeded too often.
