AUTOMOS<br />
Set the georeferencing segment<br />
Image Registration using a GCP Segment created earlier or with<br />
GCPworks (or without GCP Segment).<br />
Interactive GCP Tool for non-systematic geometric correction.<br />
Automosaic, can be used to automatically mosaic georeferenced<br />
Image databases that have the same georeferencing. This is the<br />
Most powerfull solution for full automatic mosaic generation. Output<br />
Is created automatically. Two very important subfunctions are<br />
included:<br />
TREMOV (trend removal) can be used to radiometrically balance big<br />
mosaics removing trends or hot spots in an image using APOLY2<br />
and FPOLY2.<br />
RBAL (radiometrical balancing) calculates Lookup table balancing for<br />
each scene to make the adjacent scenes match better. Resulting<br />
mosaics show less patchiness (RADNORM Programm).<br />
With the MOSTYP function the cutline can be adjusted to areas that<br />
show similar DNs – optimal cutline calculation (“Cutline”) can be<br />
adjusted using different cost functions (CFUNC).<br />
However, AUTOMOS is a complex routine and sometimes fails to<br />
complete the mosaicing process.<br />

Image Mosaicking, Moves image data from an input image database<br />
file to an output image database file. The mosaicking process may<br />
be controlled by a vector segment defining the mosaic cut-line. In<br />
addition, the input image database data may be modified by a<br />
lookup table before it is moved to the output database.<br />
Merge Image Files Merges one image channel from one or more<br />
image files to produce one output file. IMERGE overwrites one input<br />
image file with the next input file, all within the output file<br />
Histogram Matching LUT Creates a lookup table which performs<br />
histogram matching of an input image to a master image. The<br />
output lookup table is saved on the input database and can be used<br />
by program LUT to modify input image.<br />

Averaging (Mean) Filter Performs AVERAGE filtering on image data.<br />
The Averaging (mean) filter smooths image data, eliminating noise.<br />
Edge Detection Filter (up to 33x33) Performs EDGE DETECTION<br />
filtering for Image data. The edge detection filter creates an image<br />
where edges (sharp changes in grey-level values) are shown.
