Demonstrate the ability of the Clemex Vision image analysis system to discriminate and measure the spheres and their pores. The methods and operations used are discussed in the report linked at the bottom of this page (click the Download PDF link below).

The circular diameter and sphericity of complete spheres as well as the area of pores are measured during the analysis. Final results can be printed directly from Clemex Vision. Raw data are linked to their respective objects for validation purpose. Raw data can also be exported in Excel format.
