METHOD FOR IMPLEMENTING BILATERAL FILTER, AND METHOD OF DEFINING FAST APPROXIMATION BILATERAL FILTER FROM TRUE BILATERAL FILTER

摘要

PROBLEM TO BE SOLVED: To provide a fast approximate bilateral filter, FABL Filter, that permits even greater acceleration in processing speed.;SOLUTION: Multiple filters of a bilateral filter are decoupled to form into multiple linear filtering operations. The bilateral filter is represented as an approximate bilateral filter, and subjected to a logarithm whose resultant components are further subjected to a series of Jensen approximations. It is then shown that the cumulative error may be ignored without adversed affect to the result.;COPYRIGHT: (C)2011,JPO&INPIT
