A Method of Treating Impurities in the Process of Detecting Carton Black in Rubber
Xiao Bo Wang, Chuan Sheng Wang · Advanced materials research · 2013
Distinguishing carton black and impurity is important for evaluating carton black’s dispersion in rubber. There are two types of impurities, filamentous impurity and scratch. According to the characteristics of filamentous impurity, the ratio of perimeter to solidity of region and hole’s area were calculated to distinguish this type of impurity. If hole’s area was larger than 3 or the value of the ratio larger than 160, the region was regarded as filamentous impurity. Scratch was very like line, which could be identified by the way of hough translation. The treatment of impurities based on morphology is helpful for improving the accuracy of detecting carton black and calculating carton black’s dispersion.
