[GRASSLIST:874] Best methods for performing change detection

Could list members familiar with performing imagery derived change detection share some of their methodologies (specifically) and experiences (generally) using GRASS? Regarding methodologies, I do not seek step-by-step instructions as much as general overview (i.e., functions used and result expectations. Does 5.x provide inherent change detection functionality?

TIA,

Jack Varga
