Synchronous Atmospheric Correction of High Spatial Resolution Images from Gao Fen Duo Mo Satellite

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images

As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

Multi Resolution Fuzzy Segmentation of Satellite Images

Geometric Correction of Pushbroom-type High Resolution Satellite Images

This paper describes a geometric correction algorithm for high-resolution pushbroom type sensor images. In the systematic correction module, a sensor-orbit-Earth model was designed by using a vector projection technique which resulted in a forward transformation from raw image coordinates to geocentric coordinates . In order to avoid a large amount of computational load of the forward transform...

Road Extraction from High Resolution Satellite Images

Roads are significant objects of an infrastructure and the extraction of roads from aerial and satellite images are important for different applications such as automated map generation and change detection. Roads are also important to detect other structures such as buildings and urban areas. In this paper, the road extraction approach is based on Active Contour Models for 1-meter resolution g...

Building Extraction from High Resolution Satellite Images

A method for automatic building extraction from high resolution satellite image is given. First, the image is segmented by using the split and merge segmentation. Then the segmented image is filtered by applying different filters. After filtering the output raster image is converted into vector image and then the buildings are extracted on the basis of area from the vector image. Finally, the c...
