Inspired by existing works [1]-[3], in this paper we propose a novel algorithm which separately evaluates detail losses and additive impairments for image quality assessment. ...
We propose two simple quality measures to correlate detail losses and additive impairments with visual quality, respectively. ...

In the proposed metric, subtractive and additive impairments are separated and represented in the wavelet domain, and their influences to image visual quality is measured by different equations. ...
Since the amount of subtractive impairment is up-bounded by the total details within the reference image but the same limitation can't be applied to additive impairment, intuitively visual quality degradation ...
