The Effective Particles Edge Detection Method Based on Laplace
Binghui Wei, Zhi Liu · Procedia Engineering · 2012
The edge was one of the basic characteristics of an image, and showed the local characteristics of discontinuous (or mutations), such as the result of gray mutations or texture mutations, and so on. The method of extracting the particles parameters based on edge detection required that the edge of particles must be one pixel width. But the edge detected by the method of Laplace edge detection include invalid particles. And it was not exactly the single one. Therefore, this article put forward the detection method of removing the invalid particles and getting the single one edge based on Laplace.
