FUN MODEL, (ARI) 170) or breakpoint Lookup Table segment (BLUT type 172) and writing the resulting imagery back to disk. This allows bulk radiometric enhancement of image data. Image Enhancement via Functions, Generates a lookup table to perform a specified function and stores it in a database lookup table segment. Five function types are supported: Histogram Equalization, Histogram Normalization, Histogram Matching, Infrequency Brightening, Adaptive Enhancement Model Interface, zur Ausführung von Berechnungsroutinen, die im Syntax geschrieben wurden (siehe help Model, Syntax). Change Geometric Resolution: IIIAVG, IMERGE, IIIC Other options: usage of Xpace -> Reproject Focus -> Reproject Transfers image data between two database files. Input pixels are averaged, if the output database size is smaller than the input database size. Resolution reduction can be done defining the output size. Merges one image channel from one or more image files to produce one output file. Output georeferencing and pixelsize can be defined. Database to Database channel transfer. Output bounds define the new geometrical resolution.

AUTOMOS Automosaic, can be used to automatically mosaic georeferenced Image databases that have the same georeferencing. This is the Most powerfull solution for full automatic mosaic generation. Output Is created automatically. Two very important subfunctions are included: TREMOV (trend removal) can be used to radiometrically balance big mosaics removing trends or hot spots in an image using APOLY2 and FPOLY2. RBAL (radiometrical balancing) calculates Lookup table balancing for each scene to make the adjacent scenes match better. Resulting mosaics show less patchiness (RADNORM Programm). With the MOSTYP function the cutline can be adjusted to areas that show similar DNs – optimal cutline calculation (“Cutline”) can be adjusted using different cost functions (CFUNC). However, AUTOMOS is a complex routine and sometimes fails to complete the mosaicing process. MOSAIC IMERGE.eas MATCH CREMOS.EAS Image Mosaicking, Moves image data from an input image database file to an output image database file. The mosaicking process may be controlled by a vector segment defining the mosaic cut-line. In addition, the input image database data may be modified by a lookup table before it is moved to the output database. Merge Image Files Merges one image channel from one or more image files to produce one output file. IMERGE overwrites one input image file with the next input file, all within the output file Histogram Matching LUT Creates a lookup table which performs histogram matching of an input image to a master image. The output lookup table is saved on the input database and can be used by program LUT to modify input image. Mosaicing EASI routine. Noise removal: LRP DSTRIPE Line Replacement Image Destriping Frequency transforms: FTF FTI FFREQ Fourier Transformation Inverse Fourier Transformation Freq Domain Filter Database Image Filtering: FAV FED FEFROST Averaging (Mean) Filter Performs AVERAGE filtering on image data. The Averaging (mean) filter smooths image data, eliminating noise. Edge Detection Filter (up to 33x33) Performs EDGE DETECTION filtering for Image data. The edge detection filter creates an image where edges (sharp changes in grey-level values) are shown. Enhanced Frost Filtering (up to 33x33), FEFROST performs enhanced frost filtering on any type of image data. The filter is primarily used on radar data to remove high frequency noise (speckle) while preserving high frequency features (edges).
