This paper describes a novel hierarchy algorithm for extracting bridges over water in optical images. To reduce the omission of bridges by searching the edge
we extract the river regions which the bridges are included in. Firstly
we segment the optical image to get the coarse water bodies using iterative threshold
eliminate the noise regions and add the missing regions based on k-means clustering with texture information and spatial coherence. Then
the blanks are connected based on shape features and candidate bridge regions are segmented from river regions. Finally
the bridges are verified by geometric information and the ubiety between bridges and river. The results show that this approach is efficient and effective for extracting bridges in satellite image from Google Earth and in aerial optical images acquired by unmanned aerial vehicle. 2011 IEEE.
