| 摘 要： | 本文在一维单影象段跨接法的基础上,叙述了三方面的扩展:(1)将一维影象段扩展到二维影象段,从而增加了匹配单元内的信息量;(2)将面向单个特征扩展成为面向影象段;(3)将单个影象段的匹配推广到整体影象匹配,从而增加了整体的一致性。后者是将跨接法与动态规划相结合,将整体影象匹配归结为求解最优路径问题。 为了处理“遮蔽”问题或“噪声特征”,本文引入了虚拟状态的概念,它容许动态规划算法能够跨越一个或几个阶段。

| Abstract: | This paper describes three respects in which one-dimensional single image segmentbridging mode method may be extended. (1) from one-dimensional image segment totwo-dimenional segment for increasing the amount of information int he matching unit,(2) from esingle-feature-oriented to image-segment-oriented matching, and (3) fromsingle image segment matching to global image matching so as to increase the consistencyof the entire image. The last respect is concerned with the combination of the featurebridging mode me thod with dynamic programming to reduce the problem of globalimage matching into one of finding the optimal path. In order to deal with the probelm of "occlusion" or "noise feature", the paperintroduces the concept of fictitious state, which allows the dynamic programming methodto bridge over one or more stages. |
