Hyperspectral imaging technology and ENVI software were used to study eleven blurred seals in the collections of Yibin Museum. According to the matching of seal spectra with the standard pigment database, the main pigment of the seals may be cinnabar. Raman spectrometry was also used to verify the pigments of seals. Minimum Noise Fraction (MNF) and Band Math were used to process spectral image data,which improved the recognizability of the blurred seals.The recognition of seals would be helpful for research on the authors of family genealogy, the seal using habits of authors, the collection information and the value of cultural relics.
