| Abstract: | This paper presents a method for automatic extraction of seismogram by computer after analysing the characters of seismogram. It includes seismogram input by scanner, grey normalization, horizontal line removal, extractions of time marks and start time of earthquake, and intelligent tracking and thinning. In the tracking and thinning of seismogram the prior knowledge of seismogram is used effectively for improving the intelligent level of automatic extraction of seismogram. Experiments show that the method can obtain satisfy results. |
