Method Detail

applyToGrid

public void applyToGrid(Grid3D input)

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:

input - Laplacian filtered Sinogram
