A ROBUST CELLULAR PROCESSOR FOR PHASE UNWRAPPING

A new method for phase unwrapping using a lexicographically updated ce llular processor is presented. The method is robust concerning noise i nduced inconsistencies and those caused by invalid data regions. For a phase map containing small noise, the convergence time of the algorit hm is only one iteration. When a large number of inconsistencies are p resent, the proposed technique may typically take 30 to 60 whole field iterations to converge. The number of iterations required increases w ith the amount of inconsistencies in the wrapped phase map.
