Arithmetics - Subtract
This function subtracts two image sequences.
Fig. 7-12
The
Subtract
tab sheet of the
Arithmetics
dialog window must be selected.
If one or both input sequences are multichannel sequence, any number or combination can be selected.
The number of selected channels for
Input 1
and
Input 2
must be the same. They will be combined from
left to right.
This function subtracts the two image sequences
Input 1
and
Input 2
voxel by voxel and generates the
image sequence
Output
. Note that a resulting grey value may be less than 0. The parameter
Mode
determines how a range overflow (negative values) is handled.
1 - Wrap
No normalization - the grey values are displayed modulo 256 (4096). If the result is
less than 0, the value 256 (4096) is added to it.
2 - Clip
Negative values are set to 0.
3 - Normalize
The resulting grey value range is scaled to the range 0...255 (0...4095).
4 - Shift/Clip
128 (2048) is added to the difference, then negative values are set to 0. Values
greater than 255 (4095) are set to 255 (4095).
