MEDIAN FILTERING BY FAST TRANSVERSAL RECURSION

This paper begins by reviewing the median filtering procedures and then the median filtering by a Fast Transversal Recursion Technique(FTRT) is advanced. By utilizing this approach, the data ordering process can be simplified into two steps. (1) to find out the element no longer to be involved in filtering while performing the transversal revcursion ; and (2) to pinpoint the location of the element newly added. In comparison with the straight ordering methed , the calculation time to be taken for FTRT can be saved by a big margin.
