Abstract

The vast majority of human settlements have been annotated by some mapping service, like google, bing, or open street maps. However, several rural areas, specially in developing countries, are not annotated in any of the existing mapping services. Rural building mapping is important to support demographic studies and to plan actions in response to crises that affect those areas. In this project, we propose the study and development of image processing and machine learning methods for the detection and delineation of rural buildings in aerial images. Different from the annotation problem of urban constructions, rural buildings are sparsely located along large geographical areas and the amount of pre-annotated data is limited to create accurate predictive models. Hence, we propose the study and development of interactive techniques, which can iteratively improve performance as the number of supervised data increases. (AU)
