Detailed Description

performs MEM algorithm incrementally

Intended use:

Public interface

 <h3>Review Status</h3><dl><dt>Date Reviewed:<dd>yyyy/mm/dd</dl>

Prerequisite

ResidualEquation/ConvolutionEquation
LinearModel/LinearEquation Paradigm

Etymology

This class is called CEMemModel because it uses the Cornwell and Evans MEM algorithm to deconvolve the model. The "Inc" is from Incremental, as the gradient is calculated from an incremental dirty image, but the entropy is calculated from the previous model plus the deltaModel

Synopsis

This class is used to perform the Cornwell and Evans MEM Algorithm on an Array. Only the deconvolved model of the sky are directly stored by this class. The point spread function (psf) and convolved (dirty) image are stored in a companion class which is must be derived from ResidualEquation.

The deconvolution works like this. The user constructs a CEMemModel by specifying an initial model of the sky. This can by be one,two,three... dimensional depending on the dimension of the psf (see below). The user then constructs a class which implements the forward equation between the model and the dirty image. Typically this will be the ConvolutionEquation class, although any class which has a ResidualEquation interface will work (but perhaps very slowly, as the ConvolutionEquation class has member functions optimised for CLEAN and MEM)

The user then calls the solve() function (with the appropriate equation class as an arguement), and this class will perform the MEM deconvolution. The various MEM parameters are set (prior to calling solve) using the functions derived from the Iterate class, in particular setNumberIterations().

The solve() function does not return either the deconvolved model or the residuals. The solved model can be obtained using the getModel() function (derived from ArrayModel()) and the residual can be obtained using the residual() member function of the Convolution/Residual Equation Class.

The size and shape of the model used in this class MUST be the same as the convolved data (Dirty Image), stored in the companion ResidualEquation Class. However the model (and convolved data) can have more dimensions than the psf, as well as a different size (either larger or smaller). When the dimensionality is different the deconvolution is done independendtly in each "plane" of the model. (Note this has not been implemented yet but is relatively simple to do if necessary).

StokesVectors are not yet implemented.

A companion class to this one is MaskedCEMemModel. This provides the same functionality but is used with MaskedArrays which indicate which regions of the NewtonRaphson (residual) image to apply when forming the step image (MaskedCEMemModel is not yet implemented).

Example

    Matrix<Float> psf(12,12), dirty(10,10), initialModel(10,10);
    ...put appropriate values into psf, dirty, & initialModel...\.
    CEMemModel<Float> deconvolvedModel(initialModel); 
    ConvolutionEquation convEqn(psf, dirty);
    deconvolvedModel.setSigma(0.001); 
    deconvolvedModel.setTargetFlux(-2.500); 
    deconvolvedModel.setNumberIterations(30);
    Bool convWorked = deconvolvedModel.solve(convEqn);
    Array<Float> finalModel, residuals;
    if (convWorked){
      finalModel = deconvolvedModel.getModel();
      ConvEqn.residual(deconvolvedModel, finalResidual);
    }

Motivation

This class is needed to deconvolve extended images. In time, the MEM algorithm will be a principle player in the mosaicing stuff.

Template Type Argument Requirements (T)

testing: Float: lets try it first StokesVector: will require lots more work

To Do

We need to implement soft Masking
