Frequency structure analysis for IQA

2008 IEEE International Conference on Systems, Man and Cybernetics, 2008
Over the past years, research and applications of image quality assessment have attracted increasing attention. Basically, naked human eyes are the final receivers of an image and human visual system is able to extract structural information from the viewing field with high adaptation.

FR-IQA - Permutation Entropy Deviation Index

2019 IEEE Visual Communications and Image Processing (VCIP), 2019
In this work, a new objective image quality assessment (IQA) framework, based on the working principle of permutation entropy (PE) is proposed. The framework is titled as Permutation Entropy Deviation Index (PEDI). The idea is to design an IQA framework that should be highly accurate as well as computationally efficient; making it viable to be used ...

Reliability of HF/IQA, B3LYP/IQA, and MP2/IQA data in interpreting the nature and strength of interactions

Physical Chemistry Chemical Physics, 2019
Using CCSD/BBC1/IQA as a reference to describe interactions in glycol conformers, including O4⋯H6 and O3⋯O4 interactions, B3LYP/IQA data produced an exact qualitative picture and exceptionally reliable IQA energy changes, resulting in a perfectly comparable FAMSEC-based quantitative interpretation.

Self-adaptive scale transform for IQA metric

2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013
Recently, an increasing number of image quality assessment (IQA) algorithms have been developed based on multi-scale methods, such as MS-SSIM, IFC, VIF and IW-PSNR/SSIM. Inspired by the achievement of multi-scale type of IQA algorithms, this paper proposes a self-adaptive scale transform based IQA approach.

SIQA Based on 2D IQA Weighting Strategy

2020
As image quality assessment (IQA) methods for plant images have been explored thoroughly, some SIQA algorithms apply 2D IQA methods on both stereoscopic views independently and then combine the two scores to obtain an overall quality score by a dedicated strategy. The early algorithms only combine the two scores simply to obtain the final quality score,

Reduced reference IQA based on structural dissimilarity

2014 International Conference on Signal Processing and Integrated Networks (SPIN), 2014
Distortion estimation in objective domain plays an important role during Image Quality Assessment (IQA). Reduced Reference IQA requires only partial information about the reference image which can be transmitted through an ancillary data channel and is useful where complete image cannot be accessed (as reference for IQA).

iQA: An Intelligent Question Answering System

2005
Question answering (QA) is the study on the methodology that returns exact answers to natural language questions. This paper attempts to increase the coverage and accuracy of QA systems by narrowing the semantics gap between questions with terms written in abbreviations and their potential answers. To achieve this objective, the processing includes (1)

An Object IQA Framework Based on Saliency Map Similarity

2020 IEEE 6th International Conference on Computer and Communications (ICCC), 2020
Objective image quality assessment (IQA) aims to establish a mathematical model on computer to simulate human perception for image to evaluate the quality of it. This paper analyzes the image characteristics for IQA, from which gradient, spectrum, and color are selected as indexes to establish a novel IQA framework.

An Empirical View on IQA Follow-up Questions

Proceedings of the 8th SIGdial Workshop on Discourse and Dialogue, 2007
In a realistic Interactive Question Answering (IQA) situation, one third of the users pose follow-up questions, i.e., go beyond a single question per dialogue. We identify two different perspectives according to which these follow-ups can be described: informational transitions and context dependency.

357. iQA: Quality assurance management software in hospital radiology

Physica Medica, 2018
Purpose iQA takes its bases on the necessity to share QA (Quality Assurance) radiologic information among different professionals such as physician as responsible of technology, technicians and medical physicists. Our medical physics department is involved in the QA of radiologic equipment on several hospitals in the Ferrara district.
