摘要：Massive sky survey data are produced by the LAMOST large-scale survey project, which provides opportunities to search for some unusual and rare astronomical spectra. The low quality spectra still accounted for about half of total LAMOST observed data at present. For these low quality spectra, research of unusual and rare spectra recognition using computer technology must be combined with artificial check for more efficient recognition. Therefore, this paper focused on the research of interactive emission-line stars recognition. First, we use min-max normalization and continuum normalization for experimental spectra, so that there are only spectral lines features in the spectra. Then, we do feature detection on some particular spectral lines, and recognize emission-line stars through the results of spectral lines feature detection.
