Abstract

There is an upper bound for the L₁ norm of the difference of two nonnegative object functions when they both produce the same data in a digital imaging system. This bound is achieved for a certain class of systems and an arbitrary nonnegative object. For the L₂ norm of the difference, with the same conditions on the object functions, there is no upper bound.
