AN IMPROVED SYNTHETIC APERTURE RADAR IMAGE DENOISING METHOD BASED ON BLOCK-MATCHING AND 3D FILTERING [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Block-matching and 3D filtering (BM3D) are used to reduce the multiplicative coherent speckle noise of Synthetic Aperture Radar (SAR) images, which may lead to the loss of image details.

Preliminary refinement of rotation parameters of asteroids based on photogrammetric processing of on-orbit remote sensing images [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
In recent years, asteroid exploration has become an important research direction in the field of deep space exploration. The weak gravitational environment of asteroids, as well as their complex topographic, geomorphic, and dynamic characteristics, pose ...

Spatio-temporal multi-granularity : modelling and implementation challenges [PDF]

open access: yes, 2009
Multiple spatial and temporal granularities are essential to extract significant knowledge from datasets at different levels of detail: they enable to zoom-in and zoom-out a dataset, enhancing the data modelling flexibility and being instrumental to ...

Spatio-temporal join selectivity [PDF]

open access: yesInformation Systems, 2006
Given two sets S1, S2 of moving objects, a future timestamp tq, and a distance threshold d, a spatio-temporal join retrieves all pairs of objects that are within distance d at tq. The selectivity of a join equals the number of retrieved pairs divided by the cardinality of the Cartesian product S1 × S2.

Interoperability in Earth Observation deep learning: A cross-language and cross-framework evaluation

open access: yesApplied Computing and Geosciences
The Open Neural Network Exchange (ONNX) is widely promoted as a framework-independent solution for deep learning model portability, but systematic evidence of its reliability across languages, frameworks, and deployment environments remains limited for ...

Spatio-Temporal Data Construction [PDF]

open access: yesISPRS International Journal of Geo-Information, 2013
On the route to a spatio-temporal geoscience information system, an appropriate data model for geo-objects in space and time has been developed. In this model, geo-objects are represented as sequences of geometries and properties with continuous evolution in each time interval.
