    Research output: Contribution to journalArticlepeer-review


    In this paper, we show that the direct logic gate implementation of gray-scale morphology can be modified using threshold decomposition principle. The resulting new architecture has the advantage that the number of logic levels is not sensitive to structuring element size increases, yet it requires much less number of logic gates than a previously reported architecture having the same advantage.
