The Sparse Poisson Intensity Reconstruction ALgrotihms (SPIRAL) toolbox,
SPIRALTAP.m, is MATLAB code for recovering sparse signals from Poisson
observations. SPIRAL minimizes a regularized negative log-likelihood
objective function with various penalty choices for the regularization terms:
- Sparsity (l1 norm) of the coefficients in an orthonormal basis,
- Total variation seminorm of the image,
- Penalty based on Recursive Dyadic Partitions (RDPs), and
- Penalty based on translationally-invariant (cycle-spun) RDPs.

and Practice," Submitted to IEEE Transactions on Image Processing.
