Study on Urban House Information Extraction Automatically from Quick Bird Images based on Space Semantic Model

Based on the introduction to the characters and constructing flow of space semantic model, the feature space and context of house information in high resolution remote sensing image are analyzed, and the house semantic network model of Quick Bird image is also constructed. Furthermore, after region segmentation and the edge extraction to the image taking advantage of window threshold value method and Hough transformation, house information is extracted automatically from Quick Bird image through the whole space semantic model.
