BLIND ESTIMATION OF ADDITIVE NOISE VARIANCE FOR NOISY SIGNALS IN DCT DOMAIN
In many practical situations, signals are corrupted by noise and it is desired to apply filtering to remove it. For most of modern filters, it is needed to know noise variance a priori or to pre-estimate it in a blind manner in the presence of signal component. Requirements to methods of blind estim...
