Complex-valued image denosing based on group-wise complex-domain sparsity
Vladimir Katkovnik, Mykola Ponomarenko, Karen Egiazarian
Phase imaging and wavefront reconstruction from noisy observations of complex exponent is a topic of this paper. It is a highly non-linear problem because the exponent is a 2π-peri…

A novel two- and multi-level binary phase mask design for enhanced depth-of-focus
Vladimir Katkovnik, Nicholas Hogasten, Karen Egiazarian
This paper introduces a two-and multi-level phase mask design for improved depth of focus. A novel technique is proposed incorporating cubic and generalized cubic wavefront coding…
