A Method of Evaluating Carton Black's Morphology Based on Convex Hull

Given the influence of carton black's morphology on rubber's property, A new method was supplied that the parameters, such as length diameter ratio, morphology complexity, were used to characterize carton black's morphology. Convex hull of carton black’s region was used to calculate morphology complexity. Minimum bounding rectangle of carton black’s region based on convex hull was used to calculate length diameter ratio. The quantitative evaluation of carton black’s morphology is meaningful for researching the relationship between carton black’s morphology and rubber’s property.
