IPSpatDiffC
Spatial difference filter
include	"amma/Image/IPSpatDiff.hh"
User Level:	Default
Library:	IPLinear
Example:	testImageProc.cc
Section:	Image.Image Processing.Spatial_Filters
In Scope:	std

Comments:
Estimates horizontal or vertical spatial derivatives, using central differences of order 1..3.

See namespace IPSpatFilterN (or IPSpatFilterC for now) for parameter typedefs.

public DPProcessC<class InT,class OutT>

IPSpatDiffC()

Default constructor.
Creates an invalid handle.

IPSpatDiffC(UIntT Order,DirnT H_V,ResizeT Resize = Erode,PadT Pad = PadBlack)

Constructor with mask size and optional border processing and shifting

Order	difference order: implemented for values in range 1..3
H_V	difference direction: Horizontal, Vertical
Resize	o/p image size w.r.t i/p image: Erode, Original, Expand
Pad	pad extended image: PadBlack, Repeat, Reflect
Shift	if mask size is even, o/p is 1/2 pixel offset w.r.t. i/p, so 1/2 pixel shift is either: ShiftUL, ShiftDR

Notes:

• Erode option means that no special border processing is needed.

DPProcessBodyC<NumImageC<RealT>,NumImageC<RealT>> & Body()

Access body.

const DPProcessBodyC<NumImageC<RealT>,NumImageC<RealT>> & Body() const

Access body.

NumImageC<RealT> Apply(const NumImageC<RealT> & dat)

Apply operation.
NB. This may become constant in the future, but the situation isn't clear at the moment.

IntT ApplyArray(const SArray1dC<NumImageC<RealT>> & in,SArray1dC<NumImageC<RealT>> & out)

Streaming version.

const DPProcessC<NumImageC<RealT>,NumImageC<RealT>> operator=(const DPProcessC<NumImageC<RealT>,NumImageC<RealT>> & in)

Assignment operator

const DPProcessC<NumImageC<RealT>,NumImageC<RealT>> Copy() const

Make a copy of this process. Some type defs.

DPProcessBaseBodyC & Body()

Access body.

const DPProcessBaseBodyC & Body() const

Access body.

const type_info & InputType() const

Get input type.

const type_info & OutputType() const

Get input type.

BooleanT IsStateless() const

Is operation stateless ?

DPProcessBaseBodyC::ProcTypeT OpType() const

Operation type lossy/lossless.

const DPProcessBaseC & operator=(const DPProcessBaseC & oth)

Assignment operator.

const DPEntityC & operator=(const DPEntityC & dat)

Assignment.

DPEntityBodyC & Body()

Access body.

const DPEntityBodyC & Body() const

Access body.

BooleanT Save(ostream & out) const

RCAbstractC Abstract()

Create an abstract handle to this object.

BooleanT IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

BooleanT Save(ostream & out) const

Save to ostream.

RCHandleAC<DPEntityBodyC> Copy() const

Creat a deep copy of this object.
protected:

BooleanT IsValid() const

Check its a valid handle.

BooleanT IsValidObject() const

Check its a valid handle, and that the object is pointed to is also valid.

RCHandleC<DPEntityBodyC> & operator=(const RCHandleC<DPEntityBodyC> & oth)

Assignment.

BooleanT operator==(const RCHandleC<DPEntityBodyC> & oth) const

Comparison operator.

BooleanT operator!=(const RCHandleC<DPEntityBodyC> & oth) const

Comparison operator.

UIntT Hash() const

Hash function.x

BooleanT IsConst() const

Is object constant ?

BooleanT IsNotConst() const

Is object not constant ?

void SetConst(void) const

Lock the object.
This is const as a convience though it actual modified the object, often object you wish to ensure are constant already have const set. protected:

void Invalidate()

Turn this into an invalid handle.

DPEntityBodyC & Body()

Direct access to body.

const DPEntityBodyC & Body() const

Constant access to body.
