Towards Improving Segmentation of Very High Resolution Satellite Imagery
The continued advancements in satellite sensor technologies have increased the number of objects that can be discriminated within satellite imagery. Effective segmentation of high resolution satellite imagery is currently a hot topic of research. Existing segmentation algorithms and applications contain many parameters and options which require the operator to select a proper set of parameters ...
متن کاملTerrasar-x Data for Improving Geometric Accuracy of Optical High and Very High Resolution Satellite Data
Most high resolution optical images from space need ground control information (GCP) before an orthorectification can be performed. The very high geometric accuracy of geocoded data of the TerraSAR-X satellite has been shown in several investigations. This precision has been reached fully automatically without any GCP and is due to good sensor calibration, high accuracy of satellite position an...
متن کاملGeoreferencing from Orthorectified and Non-orthorectified High-resolution Satellite Imagery
The extraction of metric information from image data is highly relevant for the update of geospatial data bases. Photogrammetric methods offer tools to extract such information in a reliable and accurate manner from mostly multiple image setups using appropriate sensor models. These methods require a certain amount of expertise and often expensive software systems to process the image data. An ...
متن کاملVehicles Detection from Very High Resolution Satellite Imagery
This paper evaluates an inductive learning approach classification technique for vehicle detection and enumeration on very high resolution imagery. It tests pre-processing procedures applied to different images with different atmospheric conditions and automatic detection algorithms for detection and enumeration. This work contributes to the longer term objective that is beyond the scope of thi...
متن کاملImproving Classification Accuracy via Contextual Feature Ranking in High Spatial Resolution Satellite Imagery
Texture quantization is a useful method for extraction spatial relevance between pixels which is used in humane brain for image interpreting. Beside the spectral bands textural features of high spatial resolution data can be used to improve classification accuracy. Depends on the land cover characteristics different textural features possibly are effective from large number of available textura...
