SIDAMSubtraction
SIDAMSubtraction(w, [roi, mode, degree, direction, method, index])
Subtract background.
Parameters
w : wave
The input wave, 2D or 3D.
roi : wave
The roi (region of interest) wave. This has the same number of
rows and columns as the input wave and specifies a region of
interst. Set the pixels to be included in the calculation to 1.
Alternatively, a 2×2 wave specifying the corners of a rectanglar
roi can be also used.
mode : int {0 – 3}, default 0
The subtract mode.
- 0: plane, subtract a polynomial plane/curve from a wave.
- 1: line, subtract a value / a line from each row or column.
- 2: layer, subtract a layer from a 3D wave.
- 3: phase, subtract phase of a layer from a 3D complex wave.
degree : int, default = 1 for mode = 0, 0 for mode = 1
The degree of a subtracted plane/lines.
direction : int {0 or 1}, default 0
The direction of subtraction for mode = 1. 0 for x and 1 for y.
method : int {0 or 1}, default 0
Specify what to be subtracted from each line for mode = 1.
0 for average and 1 for median.
index : int, default 0
The layer index for mode = 2 and 3
Returns
wave
A subtracted wave.
