Automatic Stellar Spectrum Parameter Measurement Based on Similarity Measure
In stellar spectral processing, template matching method can be used to obtain comparably ideal results of stellar spectrum parameters by using pattern recognition algorithms, without computing the spectral line-index. The present paper proposed a similarity based method to measure stellar spectrum parameters automatically. First, the continuum normalization was made, and then the similarities between the stellar spectrum and the template spectrum were compared to get more accurate stellar spectrum parameters. Experiments on ELODIE spectrum showed that this method is ideal in efficiently obtaining stellar spectrum parameters.
