Multiple Feature Fusion Based Coastal Reclamation Change Detection And Target Recognition Using Optical Images

Coastal reclamation as the main way of human development and utilization of Marine resources,is an important way for human to expand space and social development.Moderate and orderly coastal reclamation,to reduce the pressure of cultivated land protection,effectively stimulating investment,adjust the distribution of Marine industrial layout and the urban construction,management,repair the waters,coastal zone and Marine ecological environment,has the vital significance.But excessive unordered coastal reclamation can greatly harm the interests of the state,causing considerable ecological environment problems.Remote sensing technology with its low cost,rapidly,accurately,widely range of earth observation ability is introduced into the coastal zone usage survey,become the powerful tools for the coastal zone usage investigation.In this paper using the high spatial resolution optical image data to study the dynamic monitoring of coastal reclamation,coastal reclamation of dynamic information in time,provide technical support to effectively safeguard the rights and interests of the state.In this paper,we study how to utilize the high image(if there is no particular high image,in this article generally refers to the high spatial resolution optical remote sensing image)quickly get coastal reclamation of information,automation identify changes area feature category,put forward a set of effective solution,the main research work is as follows:(1)Based on the analysis of the current coastal reclamation change detection method using remote sensing images,tests analysis,found that the existing remote sensing images used for reclamation around some problems of change detection.on the basis of combined with the feature of coastal reclamation high-resolution images,bring in a kind of K-mean coastal reclamation change detection algorithm of clustering analysis,the method can solve the changes in different areas on the intensity of change detection photography for the problem of different brightness scale space,and in group 2 trials coastal reclamation change detection.(2)This paper proposes a multiple feature fusion of reclamation change zone identification algorithm,is used to identify the category and the change zone,overallrecognition accuracy achieve 80.47%.
