  abstract =   "This technical report presents a heuristic
               perceptually-based termination criterion for a stochastic
               radiosity algorithms. The proposed criterion makes it
               possible to terminate the iterative radiosity simulation as
               soon as any further changes of the radiosity solution are
               predicted not to be noticed by the human observer. We use
               tone mapping operators and perceptually uniform CIE L*u*v*
               colour space to arrive at the difference of displayed
               values. In order to decide when to stop the iterations of
               the radiosity method, we evaluate the least squares fit     
                            of a power function to the error distribution
               data.",
