Automatic Building Extraction from Satellite Imagery
Automatic building extraction is an active research in remote sensing recently. It has been going on for more than 20 years but the automated extractions still encounter problems due to image resolution, variation and level of details. Mayunga et al. (2005) developed an improved snake model. However their radial casting encounters difficulties in initializing the snake model. This research pape...
متن کاملExtraction of Lakes from Satellite Imagery
We address the problem of finding the bounding contour of a lake in high-resolution satellite imagery. The proposed solution consists of a novel approach for probabilistic contour grouping when some prior (possibly rough) knowledge about the lake is known. Such knowledge is available, for example, from an existing GIS. The grouping process is based on a Bayesian approach and a constructive algo...
متن کاملOverlap-based feature weighting: The feature extraction of Hyperspectral remote sensing imagery
Hyperspectral sensors provide a large number of spectral bands. This massive and complex data structure of hyperspectral images presents a challenge to traditional data processing techniques. Therefore, reducing the dimensionality of hyperspectral images without losing important information is a very important issue for the remote sensing community. We propose to use overlap-based feature weigh...
متن کاملStructural Feature Extraction from Satellite Images
Roads, buildings and bridges are the main structural features obtained from satellite images. Detection of clouds and shadows supports the extraction of these features. Different algorithms are available for the extraction of these features, depending on the availability of remotely sensed data. In this paper, a comparative study is done for different algorithms using different types of data. I...
متن کاملPolygon Feature Extraction from Satellite Imagery Based on Colour Image Segmentation and Medial Axis
Areal features are of great importance in applications like shore line mapping, boundary delineation and change detection. This research work is an attempt to automate the process of extracting feature boundaries from satellite imagery. This process is intended to eventually replace manual digitization by computer assisted boundary detection and conversion to a vector layer in a Geographic Info...
