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 maximal-information color to gray conversion method for document images: Toward an optimal grayscale representation for document image binarization
Reza Farrahi Moghaddam, Shaohua Chen, Rachid Hedjam +1
A novel method to convert color/multi-spectral images to gray-level images is introduced to increase the performance of document binarization methods. The method uses the distribut…
