Synthesized Texture Quality Assessment via Multi-scale Spatial and Statistical Texture Attributes of Image and Gradient Magnitude Coefficients

no code implementations21 Apr 2018 S. Alireza Golestaneh, Lina Karam

Performance evaluations on two synthesized texture databases demonstrate that our proposed RR synthesized texture quality metric significantly outperforms both full-reference and RR state-of-the-art quality metrics in predicting the perceived visual quality of the synthesized textures.

Full Reference Objective Quality Assessment for Reconstructed Background Images

no code implementations12 Mar 2018 Aditee Shrotre, Lina Karam

To compare the performance of the proposed quality index with existing image quality assessment measures, we construct two different datasets consisting of reconstructed background images and corresponding subjective scores.

Quality Resilient Deep Neural Networks

no code implementations23 Mar 2017 Samuel Dodge, Lina Karam

The "experts" in our model are trained on a particular type of distortion.

Visual Saliency Prediction Using a Mixture of Deep Neural Networks

no code implementations1 Feb 2017 Samuel Dodge, Lina Karam

The final saliency map is computed as a weighted mixture of the expert networks' output, with weights determined by a separate gating network.
