Overload List
| # | Signature | Description |
|---|---|---|
| 1 | void MedianFilter(TVec *Src, TVec *Dst, TMedianState &State); | Filter data with a median filter. |
| 2 | void MedianFilter(TVec *Src, TVec *Dst, int MaskSize, int SrcIndex, int DstIndex, int Len = - 1); | Filter data in Src from SrcIndex to SrcIndex+Len with a median filter and place the result in Dst from DstIndex position on. |
| 3 | void MedianFilter(TVec *Src, TVec *Dst, int MaskSize); | Filter data in Src with a median filter and place the result in Dst. |
| 4 | void MedianFilter(TVec *Data, int MaskSize, int DataIndex = 0, int Len = - 1); | Filter data in Data with a median filter from DataIndex to DataIndex+Len and place the result back in the Data. |
Overload 1: void MedianFilter(TVec *Src, TVec *Dst, TMedianState &State);
Filter data with a median filter.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TVec * | |
| 2 | Dst | TVec * | |
| 3 | State | TMedianState & |
Filter data in Src with a median filter configured with a call to MedianInit routine and place the result in the Dst. The length of the Dst will be set to match the Length of the Src. This MedianFilter routine can be used to filter streaming data.
Each output sample is the median of the current sample and the MaskSize-1 preceding samples of the stream. The delay line is initialized to zero by SignalUtils::MedianInit and is carried across consecutive calls, so filtering a signal in chunks of any size gives the same result as filtering it in one call.
Overload 2: void MedianFilter(TVec *Src, TVec *Dst, int MaskSize, int SrcIndex, int DstIndex, int Len = - 1);
Filter data in Src from SrcIndex to SrcIndex+Len with a median filter and place the result in Dst from DstIndex position on.
MaskSize defines the size of the mask for the filter. This MedianFilter routine can be used to filter a block of data. The size of Dst is not adjusted.
Each output sample is the median of the current sample and the MaskSize-1 preceding samples; samples preceding the block are taken equal to its first sample. An even MaskSize is reduced to the next lower odd value. If MaskSize exceeds the length of Dst, it is reduced to Len.
Overload 3: void MedianFilter(TVec *Src, TVec *Dst, int MaskSize);
Filter data in Src with a median filter and place the result in Dst.
MaskSize defines the size of the mask for the filter. This MedianFilter routine can be used to filter a block of data. The size of Dst is automatically adjusted.
Each output sample is the median of the current sample and the MaskSize-1 preceding samples; samples preceding the block are taken equal to its first sample. An even MaskSize is reduced to the next lower odd value.
Overload 4: void MedianFilter(TVec *Data, int MaskSize, int DataIndex = 0, int Len = - 1);
Filter data in Data with a median filter from DataIndex to DataIndex+Len and place the result back in the Data.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Data | TVec * | |
| 2 | MaskSize | int | |
| 3 | DataIndex = 0 | int | |
| 4 | Len = - 1 | int |
Set the mask size of the median filter to MaskSize. If Len is MtxVecEOA, the maximum length of the Data vector will be used.
Each output sample is the median of the current sample and the MaskSize-1 preceding samples; samples preceding the block are taken equal to its first sample. An even MaskSize is reduced to the next lower odd value.
