ℓ 1 ball Projection onto convex sets a b s t r a c t In this article, we present a deconvolution software based on convex sets constructed from the phase of the Fourier Transform, bounded ℓ 2 energy and ℓ 1 energy of a given image. The iterative deconvolution algorithm is based on the method of projections onto convex sets. Another feature of the method is that it can incorporate an approximate total variation bound called filtered variation bound on the iterative deconvolution algorithm. The
