Abstract :
This paper proposes a new method to speed up the Resolution-Aware Fitting (RAF) algorithm. An interpolation operator is used instead of a blur operator in the RAF algorithm. The RAF algorithm with the interpolation operator is twice as fast as the RAF algorithm with the blur operator without losing fitting accuracy. It concluded that the RAF algorithm with the interpolation operator is superior to the RAF algorithm with the blur operator.
