METHOD AND APPARATUS FOR SEGMENTING PARTICLES OF ELECTRON MICROSCOPE IMAGE IN POROUS STRUCTURE

摘要

Disclosed are a method and apparatus for segmenting a particle of an electron microscope image in a porous structure. According to the present invention, the method comprises the following steps: receiving an image in a nanostructure, and estimating a boundary line by an adaptive threshold value; performing the sampling of the boundary line based on ray casting to estimate the boundary line of an actual particle on the estimated boundary line map; confirming whether the particle is detected or not; estimating circularity of the particles to select the best circular particle among the detected particles by using a predetermined equation; selecting the best circular particle among the particles by using the estimated circularity; accumulating the selected particles onto the boundary line of the boundary line map to update the map; and accumulating the selected particles onto the boundary line of the boundary line map to update a particle recognition map.;COPYRIGHT KIPO 2016
