DftFlags Enumeration

Transformation flags for cvDFT

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0

Syntax

C++

Copy

[FlagsAttribute]
public enum DftFlags

<FlagsAttribute>
Public Enumeration DftFlags

[FlagsAttribute]
public enum class DftFlags

[<FlagsAttribute>]
type DftFlags

Members

Member name	Value	Description
None	0
Inverse	1	Do inverse 1D or 2D transform. The result is not scaled. (Forward and Inverse are mutually exclusive, of course.)
Scale	2	Scale the result: divide it by the number of array elements. Usually, it is combined with Inverse.
Rows	4	Do forward or inverse transform of every individual row of the input matrix. This flag allows user to transform multiple vectors simultaneously and can be used to decrease the overhead (which is sometimes several times larger than the processing itself), to do 3D and higher-dimensional transforms etc.
ComplexOutput	16	performs a forward transformation of 1D or 2D real array; the result, though being a complex array, has complex-conjugate symmetry (CCS, see the function description below for details), and such an array can be packed into a real array of the same size as input, which is the fastest option and which is what the function does by default; however, you may wish to get a full complex array (for simpler spectrum analysis, and so on) - pass the flag to enable the function to produce a full-size complex output array.
RealOutput	32	performs an inverse transformation of a 1D or 2D complex array; the result is normally a complex array of the same size, however, if the input array has conjugate-complex symmetry (for example, it is a result of forward transformation with DFT_COMPLEX_OUTPUT flag), the output is a real array; while the function itself does not check whether the input is symmetrical or not, you can pass the flag and then the function will assume the symmetry and produce the real output array (note that when the input is packed into a real array and inverse transformation is executed, the function treats the input as a packed complex-conjugate symmetrical array, and the output will also be a real array).
