| Abstract: | Automated splitting of overlapping convex particles,especially the complex clumps,remains an important and challenging issue in image analysis,which directly affect the holistic performance.We compared and analyzed the primary steps,advantages and disadvantages,and applicability of three kinds of clump splitting methods,i.e.the concavity analysis,ellipse fitting and watershed transform.The results of anlysis indicate that(1) the splitting algorithm based on concavity analysis is limited to the simple cluste... |
