Application of Multiscale Morphological filtering and Elastic Matiching on Quasar Spectrum Recognition[J]. Journal of Image and Graphics, 1997, 2(1): 3. DOI: 10.11834/jig.19970114.
In this paper, a method about Quasar spectrum recognition is proposed. Firstly
on the signal with extreme points as its features
we introduce two important properties of multiscale morphological dilation (erosion). One is the monotone rate which is the basis of an adaptive scalar selection mechanism; the other is the monotone property which can be used to localize the features accurately by “Coarse to Fine”strategy. According to these properties
the spectrum is filtered by multiscale dilation and its features are recovered. Secondly, elastic matching is proposed to featur ever if ication and its physical meaning is pointed out. In fact
this method can be applied to other fields effectively.
