Denoising and compression in wavelet domain via projection onto approximation coefficients

31 Jul 2016Mario Mastriani

We describe a new filtering approach in the wavelet domain for image denoising and compression, based on the projections of details subbands coefficients (resultants of the splitting procedure, typical in wavelet domain) onto the approximation subband coefficients (much less noisy). The new algorithm is called Projection Onto Approximation Coefficients (POAC)... (read more)
