dc.description |
In this paper we show how a nonlinear preprocessing of speech
signal -with high noise- based on morphological filters improves the
performance of robust algorithms for pitch tracking (RAPT). This result
happens for a very simple morphological filter. More sophisticated ones could
even improve such results. Mathematical morphology is widely used in image
processing and has a great amount of applications. Almost all its formulations
derived in the two-dimensional framework are easily reformulated to be
adapted to one-dimensional context |
