Research on Evolution of Electrical Fire Melted Marks Based on Digital Image Processing Technology

This paper based on the images of the primary short circuited melted mark (PSM) and secondary short-circuited melted mark(SSM), set out to demonstrate the application of image processing in fire material evidence identification. Because there are few researches about the accurate description for image of different situation, it is difficult to further study the differences between PSM and SSM. Therefore, in this paper, the image processing technique, as an accurate description based on quantitative analysis method is put forward, and it is found that the images can be extracted out of contour and texture characteristics, which can be processed with the statistical means, so as to classify the PSM and SSM from the morphologically point of view accurately.
