An Image-Based Approach for Modeling the Copper Particle Uniformity in Formulation Design of Copper-Coated Graphite

To investigate the uniformity of copper particles in formulation design of copper-coated graphite, a quadrat-based method was presented with the image processing. Firstly, the particles were located by the foreground and background clustering algorithm. Then, an improved uniformity quantification model was established using the size and position of the particles. The findings based on the experimental results of the proposed method are as follows: the method is an effective way to quantify the uniformity by comparing with the human visual achievement; the quadrat number should be low to preserve the high performance of the method; at last, it is reasonable to use the mean uniformity in formulation design.
