It is the key technology to process image analysis  image comprehend and image depict successfully. Aim at measurement of granularity size of nonmetal grain  a new algorithm of image segmentation and parameters calculation for overlapping grain image is studied. The hypostasis of this algorithm is present some new attributes of graph sequence from discrete attribute of graph  consequently achieve that pick up the geometrical characteristics from input graph  and new graph sequence which in favor of image segmentation is recombined. The conception that image edge denoted with "twin-point" is put forward  base on geometrical characters of point  image edge is transformed into serial edge  and on recombined serial image edge  based on direction vector definition of line and some additional restricted conditions  the segmentation twin-points are searched with  thus image segmentation is accomplished. Serial image edge is transformed into twin-point pattern  to realize calculation of area and granularity size of nonmetal grain. The inkling and uncertainty on selection of structure element which base on mathematical morphology are avoided in this algorithm  and image segmentation and parameters calculation are realized without changing grain's self statistical characters.   Morphology, Nature and Formation Mechanism of Packet Plate Martensite in Medium and High Carbon Steels (CPCI-S收录) 会议论文 FRONTIERS OF MANUFACTURING AND DESIGN SCIENCE II, PTS 1-6 作者:  Ma, Yuexin[1];  Liu, Yuejun[2];  Wang, Long[1];  Zeng, Dechang[3];  Tan, Yuhua[4] 收藏  |  浏览/下载：1/0  |  提交时间：2019/04/15 martensite  packet martensite  plate martensite  phase transformation mechanism  twin boundary packet mechanism
