【摘要】 本文分析了形态滤波器输出信号的局部特性，给出了在某一点输出信号值等于输入信号值的条件。指出形态滤波器的输出信号在一定的范围内呈现局部单调性，并且这种单调性是可预测的。更多还原

【Abstract】 We analyse some properties of morphological filtered signals. We derive the conditions in which a signal is invariant to morphological filters. Then we point out that morphological filtered signals are locally monotonic in certain regions and the monotonicity can be predicted.更多还原
