针对地标显著度模型的构成、计算方法及存在的突出问题,该文在对国内外大量文献进行分析研究的基础上,系统综述了基于显著度模型提取地标的方法。指出了现有研究中存在的主要问题和不足,围绕感知显著度、认知显著度、上下文显著度、总体显著度的计算方法,进行了较为深入的研究,并针对性地提出了解决方案。
Aiming at the structure, calculation method and the outstanding problems of the landmark model, based on the analysis of a large number of domestic and international literatures, this paper re- viewed the research progresses in extracting landmarks based on salience model. Problems of existing methods were summarized and analyzed. The calculation methods of the perceptual salience, the cognitive salience and the context salience which compose the landmark salience were studied deeply, and solution to solve the problem was put forward.
