Remote Sensing Digital Images Processing Introduction of Remote Sensing Digital Images Image Preprocessing Image Enhancement Image Integration Introduction of Remote Sensing Digital Images Remote Sensing Digital Images Images Resolution Spectral resolution The wavelength width of the different frequency bands recorded. Images Resolution Radiometric resolution The number of different intensities of radiation the sensor is able to distinguish. Images Resolution Spatial resolution The size of a?pixel?that is recorded in a?raster image Images Resolution Temporal resolution A performance index of the remote sensing image time interval. Color Composite Image Preprocessing Radiometric corrections Atmosphere corrections Geometric corrections Image Preprocessing Radiometric corrections Image Preprocessing Image Preprocessing Image Preprocessing Atmosphere corrections Image Preprocessing Geometric corrections Image Enhancement Contrast Enhancement Spatial Filtering Image Transformations Principal Components Analysis Contrast enhancement linear contrast stretch Spatial filtering Spatial filtering Image Transformations Image transformations generate “new” images from two or more sources which highlight particular features or properties of interest, better than the original input images. Principal Components Analysis The objective of this transformation is to reduce the dimensionality in the data, and compress as much of the information in the original bands into fewer bands. Image Integration The image integration Temporal resolution Spatial resolution Different sensor Different types Original Images took from the same place and different time The result of SPOT-5 and RADARSAT-2 The result of QuickBird and RADARSAT-2 Three-dimensional perspective views Integrated by DEM and remote sensing image please give some questions Any more information * Remote Sensing Digital Images Processin
