FSITM: A Feature Similarity Index For Tone-Mapped Images

no code implementations19 Apr 2017 Hossein Ziaei Nafchi, Atena Shahkolaei, Reza Farrahi Moghaddam, Mohamed Cheriet

In this work, based on the local phase information of images, an objective index, called the feature similarity index for tone-mapped images (FSITM), is proposed.

MUG: A Parameterless No-Reference JPEG Quality Evaluator Robust to Block Size and Misalignment

no code implementations12 Sep 2016 Hossein Ziaei Nafchi, Atena Shahkolaei, Rachid Hedjam, Mohamed Cheriet

The proposed metric called median of unique gradients (MUG) is based on the very simple facts of unique gradient magnitudes of JPEG compressed images.

Mean Deviation Similarity Index: Efficient and Reliable Full-Reference Image Quality Evaluator

no code implementations26 Aug 2016 Hossein Ziaei Nafchi, Atena Shahkolaei, Rachid Hedjam, Mohamed Cheriet

Motivated by a recent work that utilizes the standard deviation pooling, a general formulation of the DP is presented in this paper and used to compute a final score from the proposed GS and CS maps.

Deviation Based Pooling Strategies For Full Reference Image Quality Assessment

no code implementations26 Apr 2015 Hossein Ziaei Nafchi, Rachid Hedjam, Atena Shahkolaei, Mohamed Cheriet

In this paper, we propose to use the mean absolute deviation (MAD) and show that it is a more robust and accurate pooling strategy for a wider range of IQAs.
