Linear Island Alignment Recognition Based on Gestalt Principle

The Gestalt cognition psychology plays an important role in the recognition of linear island alignment by several perceptual grouping principals,namely the law of proximity,compactness,good continuation.Based on the perceptual grouping principles mentioned above,a new method has been developed for linear island alignment recognition.The spatial neighborhood analysis is first conducted by Delaunay triangulation.And based on the neighborhood graph,the corresponding MST is generated to represent spatial structure of island cluster.Then the edge of MST tree is pruned successively according to three different Gestalt conditions.The experiment shows that result is consistent with the manual identification.
