Poisson Approximation of Image Processes in Computer Tomography
We present estimations and asymptotic expansions for the total variation distance between the superposition of independent Bernoulli point processes and the Poisson point process with the same intensity measure. Special emphasis is given to the lattice case which arises in connection with the image reconstruction in computer tomography.
