...Two methods are often used for selection of thresholds (Singh 1989, Deer 1995, Yool et al. 1997): (1) interactive procedure or manual trial-and-error procedure—an analyst interactively adjusts the thresholds and evaluates the resulting image until satisfied; and (2) statistical measures— selection…...

...A couple of years later (Singh 1989), he reviewed that statement and concluded that the regression method performed only marginally better than univariate image differencing techniques in detecting tropical forest cover changes....
