X-Ray Fluorescence Spectral Inspection of Plastic Express Packaging Bags Based on K-means and Within-Cluster Sum of Squared Errors
The method for identifying and classifying plastic express bags as the physical evidences commonly seen at crime scenes is proposed to promote the public security investigation. By means of X-ray fluorescence spectroscopy, the element types and contents of 60 plastic express bag samples with different origins and brands are tested. Meanwhile, the qualitative and semi-quantitative analysis is performed according to the spectral data, so that the 60 samples are preliminarily divided into 13 categories. Based on the within-cluster sum of squared errors (SSE), the relationship between SSE and number of clusters
