A comprehensive evaluation of full reference image quality assessment algorithms [PDF]
2012 19th IEEE International Conference on Image Processing, 2012 Recent years have witnessed a growing interest in developing objective image quality assessment (IQA) algorithms that can measure the image quality consistently with subjective evaluations. For the full reference (FR) IQA problem, great progress has been made in the past decade.

Full-reference calibration-free image quality assessment [PDF]
Signal Processing: Image CommunicationOne 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 this reason, usually IQA metrics undergo a calibration process based on subjective quality examples. However, example-based training makes generalization problematic, hampering

Blind full reference quality assessment of poisson image denoising
2014 IEEE International Conference on Image Processing (ICIP), 2014 The distribution of real camera sensor is well approximated by Poisson, and the estimation of the light intensity signal from the Poisson count data plays a prominent role in digital imaging. It is highly desirable for imaging devices to carry the ability to assess the performance of Poisson image restoration. Drawing on a new category of image quality

Full-Reference Calibration-Free Image Quality Assessment [PDF]
, 2022 <p>The paper proposes the use of a scoring function which is inspired to fundamental principles and theoretical constraints and is parametrized by the viewing distance. The common final step of image quality assessment methods is the mapping of an objective metric onto a subjective scale using a parametric, empirical non-linear scoring function ...

New Combined Metric for Full-Reference Image Quality Assessment
SymmetryIn recent years, many new metrics highly correlated with the Mean Opinion Score (MOS) have been proposed for assessing image quality through Full-Reference Image Quality Assessment (FR-IQA) methods, such as MDSI, HPSI, and GMSD. Eight of these selected metrics, which compare reference and distorted images in a symmetrical manner, are briefly described ...

Blockiness Estimation in Reduced Reference Mode for Image Quality Assessment [PDF]
, 2014 In this paper we present blockiness estimation meter in reduced reference mode using frequency domain analysis. Since blockiness is an abrupt luminance discontinuity at the DCT block boundaries and also has periodic patterns, therefore blockiness ...

Full-Reference Image Quality Assessment Measure Based on Color Distortion
, 2015 The purpose of this paper is to introduce a new method for image quality assessment (IQA). The method adopted here is assumed to be Full-reference measure. Color images that are corrupted with different kinds of distortions are assessed by applying a color distorted algorithm on each color component separately.
