Abstract:

Based on the characteristics of high spatial resolution images, an object-oriented approach to the building extraction is proposed. The method takes the object as a processing unit to perform classification using the rich information such as the spectrum, the object shape, and the implicit space semantic relations embedded in the images. The classification result is optimized based on the characteristics of the spatial relationship. Edges between different categories are modified using mean filtering. Experiments show that the object-oriented method can provide relatively complete extraction of the building, and improve precision of the extraction.

Key words: object-oriented, high resolution image, multi-scale image segmentation, spatial relationship
