In this article, we have reviewed the reasons why we (collectively) want to love or leave the
venerable (but perhaps hoary) MSE. We have also reviewed emerging alternative signal …

Signal-to-noise ratio generically means the dimensionless ratio of the signal power to the
noise power contained in a recording. Abbreviated SNR by engineers and scientists, the …

Minimization of the error probability to determine optimum signals is often difficult to carry
out. Consequently, several suboptimum performance measures that are easier than the …

My thesis models feedback-based error control schemes. Initially I proposed to use Peak-
Signal-to-Noise-Ratio (PSNR) as video quality metric because of its simplicity. However, it is …

This paper studies two increasingly popular paradigms for image quality assessment-
Structural SIMilarity (SSIM) metrics and Information Fidelity metrics. The relation of the SSIM …

This paper reviews the basic background knowledge necessary to design effective no-
reference (NR) quality estimators (QEs) for images and video. We describe a three-stage …

Perceptual image quality metrics have explicitly accounted for human visual system (HVS)
sensitivity to subband noise by estimating just noticeable distortion (JND) thresholds. A …

We propose a best basis algorithm for signal enhancement in white Gaussian noise. The
best basis search is performed in families of orthonormal bases constructed with wavelet …

One of the changes that modern digital communications systems has brought to radio
engineering is the need for end-to-end performance measurements. The measure of that …

Heavy criticism has been directed against using peak signal-to-noise ratio (PSNR) as a full
reference quality metric for digitally processed images and video, since many studies have …
