Method Detail

applyToGridLap2D

public void applyToGridLap2D(Grid2D sino)

Use this method in combination with the Laplace2D Filter. This method searches for the collimator borders in a laplacian filtered image. The current implementation searches in each detector for the first and last non-zero element. The coordinates with the maximum number of non-zero elements across all projections are then assumed to be the borders and set to zero.

Parameters:

sino - Laplacian filtered Sinogram

applyToGridLap1D

public void applyToGridLap1D(Grid2D sino)

Use this method in combination with the Laplace1D Filter. This method searches for the collimator borders in a laplacian filtered image. The current implementation searches in each detector for the first and last non-zero element. The coordinates with the maximum number of non-zero elements across all projections are then assumed to be the borders and set to zero.

Parameters:

sino - Laplacian filtered Sinogram

applyToGridLap1D

public void applyToGridLap1D(Grid3D input)

Use this method in combination with the Laplace1D Filter This method searches for the collimator borders in a laplacian filtered image. The current implementation searches in each detector for the first and last non-zero element. The coordinates with the maximum number of non-zero elements across all projections are then assumed to be the borders and set to zero.

Parameters:

input - Laplacian filtered Sinogram

applyToGridLap2D
