2. Impact of Topography on the Geome- Try of a Tm Scene

چکیده
Methodologies to improve Landsat TM forest classifications of alpine regions through the removal of some radiometric and geometric distortions are tested. Besides correcting for sensor and system induced errors, geometric corrections are performed using a digital elevation model. Then scene related effects such as differences in illumination as well as the height dependent atmospheric influence and adjacency effects are corrected.The obtained improvement of the forest classification accurary can be demonstrated against excellent ground truth.

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
متن کاملScene context dependency of pattern constancy of time series imagery
A fundamental element of future generic pattern recognition technology is the ability to extract similar patterns for the same scene despite wide ranging extraneous variables, including lighting, turbidity, sensor exposure variations, and signal noise. In the process of demonstrating pattern constancy of this kind for retinex/visual servo (RVS) image enhancement processing, we found that the pa...

Following the influential Nordhaus (1975) article, investigation of the influence of political variables on the macroeconomic ones became an interesting subject matter for economic analyses. In this regard, the impact of elections on economic variables, which in the economic literature has been interpreted as “election cycles”, is one of the most prominent political phenomena. Policymakers, aim...
