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.
