Offset Name Type Description
0x00 type short int Region type (BASELINE = 0, SEGMENTATION = 1, SEGMENTA-
TION DIFF= 2)
0x02 numInVertices short int Number of vertices defining the inside polygon for difference regions.
This is also used to store the number of vertices for the other regions.
0x04 numOutVertices short int Number of vertices defining the outside polygon. Only used for difference
regions, in all other cases this should be set to 0.
0x06 padding short int Padding bytes, set to 0.
Table A.7: The regions entry.
Offset Name Type Description
0x00 columnCoordinate float Floating point column coordinate of this vertex.
0x04 rowCoordinate float Floating point row coordinate of this vertex.
Table A.8: The vertex entry.
Offset Name Type Description
0x00 maskKey int The key the images use to refer to this mask. An unique integer to be used as
key in the mask map.
0x04 xMaskSize int If in gird mode only between the outboard intersections is masked, this field stored
the size of the correction mask in x-direction. Else this value is equal to x-size of
one image.
0x08 yMaskSize int If in gird mode only between the outboard intersections is masked, this field stored
the size of the correction mask in y-direction. Else this value is equal to y-size of
one image.
0x0C padding short Padding bytes, set to 0
Table A.9: The noise correction mask header.
