A Threshold is used to pass a threshold value to detection algorithms.
The threshold may be a simple value (type == VALUE), or in units of the image standard deviation. Alternatively you may specify that you'll provide the standard deviation (type == STDEV) or variance (type == VARIANCE)
Note that the constructor is not declared explicit, so you may pass a bare threshold, and it'll be interpreted as a VALUE.
