摘要
本文提出了图象匹配的一种量度 ,这种图象匹配的量度既考虑了差异信号的积累及其分布 (结构 )的特点 ,还考虑了异常差异信号的处理 .同时提出了基于图象匹配量度的扫描地形图中对称形状要的素提取算法 .通过实际算例 ,验证了所提出匹配量度和所算法的有效性与实用性 。
This paper presents a new measurement of image matching. The measurement takes account of accumulation of discrepancy signals, distribution of discrepancy signals, and treatment of preternatural discrepancy signals. Based on the measurement, this paper presents, at the same time, a new algorithm for extracting features with symmetric figure on scanned topographic map. Effectiveness and practicability of the new measurement and the new algorithm are explained by some actual examples. It is important for vectoring of scanned topographic map and theory of pattern recognition.
