An Object-oriented Approach for Extracting |Farm Waters within Coastal Belts
面向对象的海岸带养殖水域提取

A feasible object-oriented farm water extraction method is proposed.This approach includes the following steps.First,a multi-resolution image segmentation method combining spectral and shape features is implemented to extract image parcels.Second,a set of parcel features including spectral,shape,spatial relationships are obtained for the succeeding analyses.Third,the whole water areas and then the polygonal water areas and linear water areas are extracted with multi-feature analyses.In the last step,the farm waters are extracted by eliminating polygonal water area and linear water areas.Our method is validated with experimental analyses.
