MUG: A Parameterless No-Reference JPEG Quality Evaluator Robust to Block Size and Misalignment
Hossein Ziaei Nafchi, Atena Shahkolaei, Rachid Hedjam +1
In this letter, a very simple no-reference image quality assessment (NR-IQA) model for JPEG compressed images is proposed. The proposed metric called median of unique gradients (MU…
Mean Deviation Similarity Index: Efficient and Reliable Full-Reference Image Quality Evaluator
Hossein Ziaei Nafchi, Atena Shahkolaei, Rachid Hedjam +1
Applications of perceptual image quality assessment (IQA) in image and video processing, such as image acquisition, image compression, image restoration and multimedia communicatio…
A Note on Efficiency of Downsampling and Color Transformation in Image Quality Assessment
Hossein Ziaei Nafchi, Mohamed Cheriet
Several existing and successful full reference image quality assessment (IQA) models use linear color transformation and downsampling before measuring similarity or quality of imag…
Deviation Based Pooling Strategies For Full Reference Image Quality Assessment
Hossein Ziaei Nafchi, Rachid Hedjam, Atena Shahkolaei +1
The state-of-the-art pooling strategies for perceptual image quality assessment (IQA) are based on the mean and the weighted mean. They are robust pooling strategies which usually…
