TVecByte.Median Method

Overload List

#	Signature	Description
1	function Median(const Src: TMtxVecInt; MaskSize: Integer): TVecInt;	Applies median filter with size Mask to data in Src and stores the result in the calling vector.
	└ indexed: function Median(const Src: TMtxVecInt; MaskSize: Integer; SrcIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;
2	function Median(MaskSize: Integer): TVecInt;	Applies median filter with size Mask to the calling vector.
	└ indexed: function Median(MaskSize: Integer; Index: Integer; Len: Integer): TMtxVecInt;
3	function Median: Integer;	Median.
	└ indexed: function Median(Index: Integer; Len: Integer): Integer;

Overload 1: function Median(const Src: TMtxVecInt; MaskSize: Integer): TVecInt;

Applies median filter with size Mask to data in Src and stores the result in the calling vector.

#	Name	Type	Description
1	Src	TMtxVecInt	source TVecInt or TMtxInt
2	MaskSize	Integer

Result: stored in self (calling object), returns self for chaining

Remarks:

Median filter is a nonlinear filter which replaces each element of the calling vector with the median value, calculated over the fixed range (mask) centered around that element and stores the result in the calling vector.

Indexed: function Median(const Src: TMtxVecInt; MaskSize: Integer; SrcIndex: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Applies median filter with size Mask to Src object elements [SrcIndex..SrcIndex+Len-1] and stores the result in the calling vector elements [Index..Index+Len-1].

#	Name	Type	Description
1	Src	TMtxVecInt	source TVecInt or TMtxInt
2	MaskSize	Integer
3	SrcIndex	Integer	source start index
4	Index	Integer	start index
5	Len	Integer	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

Median filter is a nonlinear filter which replaces each element of the Src vector with the median value, calculated over the fixed range (mask) centered around that element and stores the result in the calling vector.

Overload 2: function Median(MaskSize: Integer): TVecInt;

Applies median filter with size Mask to the calling vector.

#	Name	Type	Description
1	MaskSize	Integer

Result: stored in self (calling object), returns self for chaining

Remarks:

Median filter is a nonlinear filter which replaces each element of the calling vector with the median value, calculated over the fixed range (mask) centered around that element.

Indexed: function Median(MaskSize: Integer; Index: Integer; Len: Integer): TMtxVecInt;

Applies median filter with size Mask to the calling vector elements [Index.. Index+Len-1].

#	Name	Type	Description
1	MaskSize	Integer
2	Index	Integer	start index
3	Len	Integer	element count

Result: stored in self (calling object), returns self for chaining

Remarks:

Median filter is a nonlinear filter which replaces each element of the calling vector with the median value, calculated over the fixed range (mask) centered around that element.

Overload 3: function Median: Integer;

Median.

Returns: Int32

Remarks:

Calculate median value for all calling object elements.

Examples

var a: Matrix;
    c: double;
begin
    a.SetIt(1,4,False,[1,2,3,4]);
    c := a.Median;
end;

Indexed: function Median(Index: Integer; Len: Integer): Integer;

Calculate median value for calling vector elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	Index	Integer	start index
2	Len	Integer	element count

Returns: Int32

Remarks:

An exception is raised if TMtxVecBase.ConditionCheck is true and array borders are overrun.
