Detailed Description

mitkFootprint1DGaussian - concrete class for one dimensional footprint with Gaussian kernel

mitkFootprint1DGaussian is a concrete class to encode and decode one dimensional footprint table using Gaussian kernel. The Gaussian footprint function is as follows: footprint(x,y) = coeff * exp{-[(x,y) * F^(-1) * (x,y)']/adjustradii} , where "coeff" is the weight coefficient, adjustradii is the adjust radii coefficient, _ _ | vmatrix[0] vmatrix[2] | and "F" is the variance matrix = | | |_ vmatrix[1] vmatrix[3] _| the code snippet to use this class is:

    mitkFootprint1DGaussian *footprint = new mitkFootprint1DGaussian;
    footprint->SetCoefficient(coeff);
    footprint->SetAdjustRadii(adjustradii);
    footprint->SetVarianceMatrix(vmatrix);
    footprint->SetRadiiSquare(rs);
    footprint->SetSampleNumber(num);
    table = footprint->EncodeFootprintTable();
    .....
    if(table)
      { value = footprint->DecodeFootprintTable(x, y); }
