基于一种改进的Hough变换的输电线提取与识别

运用西方叙述学中文类的观念，来分析道教东晋上清仙传的名称体例、语言笔法与意象结构上所表现的叙述内涵与特质，以凸显其作为宗教别传的文学意义与“修与报”的结构功能。首先，探讨其内传命名的区隔性与传信性，内传撰阅的封闭性与神圣性，以及所表现的形式体例特质。其次，分析其结合宗教体验与文学美感所形成的诗的、象征的、神话的宗教语言，以及叙述虚实笔法与情节发展的结构性关系，所具显的“既是宗教又是文学”的艺术美感。最后，解析文本中感官字词描述所呈现的丰富文学意象，以及修炼与仪式所蕴含的叙述结构，推定其应颇合乎“奇幻叙述体”的叙述审美特色。

Extraction and Recognition of Transmission Line Based on an Improved Hough Transform

The transmission line image taken from field environment presents linear character obviously, so it can be regarded as a line to extract and recognize. The Hough transform is a general technique for identifying the location and orientation of certain types of feature in a digital image. From the properties of power lines and Hough transform, the morphological analysis and searching clustering method were used to remove the noise of power line edge image. And then, the power line pixel points were used to estimate the adaptive threshold interval according to certain rules. Finally, the power line was detected from these pixels using the obtained threshold interval. The experimental results show that the proposed method can extract and recognize the transmission lines with simple calculation and high speed.
