Query: Quantitative Analysis of Particles Segregation   Segregation is a popular phenomenon. It has considerable effects on material
performance. To the author's knowledge, there is still no automated objective
quantitative indicator for segregation. In order to full fill this task,
segregation of particles is analyzed. Edges of the particles are extracted from
the digital picture. Then, the whole picture of particles is splintered to
small rectangles with the same shape. Statistical index of the edges in each
rectangle is calculated. Accordingly, segregation between the indexes
corresponding to the rectangles is evaluated. The results show coincident with
subjective evaluated results. Further more, it can be implemented as an
automated system, which would facilitate the materials quality control
mechanism during production process.
