A study of object-oriented extracting edge of hazard-affected body in remote sensing image

It is an important aspect of studying hazard-affected body of geological hazards.Extracting surface feature automatically based on high-resolution remote sensing image will be an important way to distinguish hazard-affected body of geological hazards.On the basis of a method of object-oriented,the hazard-affected body object is formed in the high resolution remote sensing image which is segmented.The complete edge of hazard-affected body object is extracted from the hazard-affected body image wh...
