Gauge-Fixing the Forward-Forward Objective: A Whitened Goodness Derived from a Likelihood-Ratio Account
Paolo Giannitrapani
The Forward-Forward algorithm trains each layer locally, so that a scalar goodness - the sum of squared activations - is high on real inputs and low on contrastive ones. Under an e…
Partial-Reference IQA Based on Hermite-Gauss Structural Prediction and Texture Deviation
Paolo Giannitrapani, Elio D. Di Claudio, Giovanni Jacovitti
We propose PreSPA (Partial-Reference Structural Prediction Approach), a Partial-Reference Image Quality Assessment framework that decomposes perceptual quality into two complementa…
BELE: Blur Equivalent Linearized Estimator
Paolo Giannitrapani, Elio D. Di Claudio, Giovanni Jacovitti
In the Full-Reference Image Quality Assessment context, Mean Opinion Score values represent subjective evaluations based on retinal perception, while objective metrics assess the r…
Full-Reference Calibration-Free Image Quality Assessment
Elio D. Di Claudio, Paolo Giannitrapani, Giovanni Jacovitti
One major problem of objective Image Quality Assessment (IQA) methods is the lack of linearity of their quality estimates with respect to scores expressed by human subjects. For th…
Predicting the Blur Visual Discomfort for Natural Scenes by the Loss of Positional Information
Elio D. Di Claudio, Paolo Giannitrapani, Giovanni Jacovitti
The perception of the blur due to accommodation failures, insufficient optical correction or imperfect image reproduction is a common source of visual discomfort, usually attribute…
