The
algorithm is fast in computation time and was implemented
in the X-ray scanner for real-time quarantine inspection at
a scanning rate of 1.2 m/min. Suspected sites of infestation
inside fruit can be accurately marked on the acquired X-ray
image to aid the quarantine officer during inspection. For
different kinds of fruits, initial tests and choices of operation
parameters need to be determined, including number of
iterations for morphological filtering, operational sub-image
size, and interpolation grid size
