Research of sparse representation method for ringing suppression

Computer Optics. 2016. Vol. 40. No. 6. P. 895-903.
Umnov A., Krylov A. S.

In this paper we suggest an algorithm for ringing suppression based on a sparse 
representation method. As one of its steps, the suggested method includes image deblurring 
based on the Wiener-Hunt deconvolution algorithm. The ringing suppression algorithm uses 
the signals' mutual coherence and sparsities analysis when dealing with the ringing effect 
based on the sparse representation method. We also analyze the mutual coherence and 
sparsities for blurred images and images with white Gaussian noise.
