addImage()

void ossimAtbMatchPoint::addImage

(

ossimGridRemapSource *

image_source

)

Adds a new contribution to the sample set.

Definition at line 43 of file ossimAtbMatchPoint.cpp.

   //***
   // Assure that this image contains the view point corresponding to this
   // matchpoint:

   if (traceExec())  CLOG << "returning..." << endl;
   return;
}

assignRemapValues()

bool ossimAtbMatchPoint::assignRemapValues

(

)

The target parameter value computed given all contributions. Returns true if a valid quantity is returned.

Definition at line 79 of file ossimAtbMatchPoint.cpp.

{
   static const char MODULE[] = "ossimAtbMatchPoint::assignRemapValues()";
   if (traceExec())  CLOG << "entering..." << endl;

   //***
   // Determine the number of contributors. We require minimum of two:
   //***
   ossim_uint32 num_contributors = (ossim_uint32)thePointSourceList.size();
   if (num_contributors < 2)
      return false;

   //***
   // Hand off the computation of the target pixel to the ATB engine being
   // used. The engine implements the methods for computing targets, as these
   // will vary according to algorithm being used:
   //***
   theGridRemapEngine->assignRemapValues(thePointSourceList);

   if (traceExec())  CLOG << "returning..." << endl;
   return true;
}

setGridRemapEngine()

void ossimAtbMatchPoint::setGridRemapEngine

(

ossimGridRemapEngine *

engine

)

Sets the ATB remap engine reference owned by the controller. This engine is the only object that understands how to compute remap parameters from pixel data. This permits easily modifying the ATB algorithm without the support classes such as this one.

Definition at line 128 of file ossimAtbMatchPoint.cpp.

{
   static const char MODULE[] = "ossimAtbMatchPoint::setAtbRemapEngine";
   if (traceExec())  CLOG << "entering..." << endl;

   theGridRemapEngine = engine;
   
   //***
   // Need to communicate this change of engine to the point sources that use
   // it to arrive at a "source value":
   //***
   vector<ossimAtbPointSource*>::iterator source = thePointSourceList.begin();
   while (source != thePointSourceList.end())
   {
      (*source)->setGridRemapEngine(engine);
      source++;
   }

   if (traceExec())  CLOG << "returning..." << endl;
   return;
}

setKernelSize()

void ossimAtbMatchPoint::setKernelSize

(

int

side_size

)

Hook to set the size of the kernel used by all point sources in computing their mean pixel value. The kernels will be resized to NxN.

Definition at line 110 of file ossimAtbMatchPoint.cpp.

{
   static const char MODULE[] = "ossimAtbController::setKernelSize(N)";
   if (traceExec())  CLOG << "entering..." << endl;

   vector<ossimAtbPointSource*>::iterator psi = thePointSourceList.begin();
   while (psi != thePointSourceList.end())
      (*psi)->setKernelSize(side_size);

   if (traceExec())  CLOG << "returning..." << endl;
   return;
}

viewPoint()

const ossimDpt& ossimAtbMatchPoint::viewPoint ( ) const

inline

Returns the point in view coordinates associated with this object.

Definition at line 48 of file ossimAtbMatchPoint.h.

{ return theViewPoint; }
