Image Quality Assessment using Elman Neural Network Model and Interleaving Method
free download

ABSTRACT Imaging systems introduce distortions and artifacts to the image. It is crucial to know the quality of the image before processing. In any image processing application it is important to know reliability of the imaging system and the quality metrics of the image 

Image quality assessment of the right ventricle with three different delayed enhancement sequences in patients suspected of ARVC/D
free download

ABSTRACT Histopathologic findings in arrhythmogenic right ventricular cardiomyopathy/ dysplasia (ARVC/D) are replacement of the normal myocardium with fatty and fibrous elements with preferential involvement of the right ventricle. The right ventricular fibrosis 

Image-quality assessment method for digital phase-contrast imaging based on two-dimensional power spectral analysis
free download

ABSTRACT With use of the phase shift of X-rays that occurs when they pass through an object, phase-contrast imaging (herein referred to as phase imaging) can produce images different from those of conventional contact imaging (herein referred to as conventional 

Image Moment based Wavefront Sensing for In situ Full-field Image Quality Assessment
free download

ABSTRACT A new concept of using focus-diverse point spread functions (PSF) for modal wavefront sensing (WFS) is explored. This concept is based on relatively straightforward image moment analysis of measured PSFs, which differentiates it from other focal-plane 

Technical assessment of a cone-beam CT scanner for otolaryngology imaging: Image quality, dose, and technique protocols
free download

Purpose: As cone-beam CT (CBCT) systems dedicated to various imaging specialties proliferate, technical assessment grounded in imaging physics is important to ensuring that image quality and radiation dose are quantified, understood, and justified. This paper 

Online Crowdsourcing Subjective Image Quality Assessment

ABSTRACT Recently, HodgeRank on random graphs has been proposed as an effective framework for multimedia quality assessment problem based on paired comparison method. With the random design on large graphs, it is particularly suitable for large scale 

Image Quality Assessment Method Based on Support Vector Machine and Particle Swarm Optimization
free download

In order to improve the assessment accuracy of white noise, Gauss blur, JPEG2000 compression and other distorted images, this paper puts forward an image quality assessment method based on support vector machine and particle swarm optimization. 

Image quality assessment using different types of optical diffusers for photoacoustic tomography
free download

ABSTRACT We have investigated different types of optical diffusers for the image quality assessment of photoacoustic tomography (PAT). PAT has been adapted in many biomedical research efforts over the past decade, however, studies on image quality of PAT have not 

Image Quality Assessment Using the Motif Scan
free download

ABSTRACT Image quality assessment (IQA) evaluates the quality of an image by computing the difference between the reference and distorted images. This paper proposes an image quality metric (IQM) that uses the motif scan. Since edges often contain much information 

Reduced-reference Image Quality Assessment Based on Roberts Derivative Statistic Model of Natural Image?
free download

ABSTRACT The measurement of Reduced-reference (RR) image quality aims in predicting the visual quality of distorted images with only partial information from the reference images. In this paper, we propose a RR image quality assessment method based on Roberts cross

A New Assessment Measure of Shadow Image Quality Based on Error Diffusion Techniques
free download

ABSTRACT A formal approach to study quality of shadow images in secret image sharing schemes based on error diffusion techniques is introduced. A novel secret sharing quality measure for assessment of shadow image quality, namely average flipping rate (AFR), 

Image Quality Assessment based on Perceptual Blur Metric
free download

ABSTRACT The recent development of digital image acquisition technologies leads to better image quality, in terms of spatial resolution and sensitivity. Image quality is a characteristic of an image that measures the perceived image degradation. Several techniques and 

A Medical Image Watermarking Technique for Embedding EPR and Its Quality AssessmentUsing No-Reference Metrics
free download

ABSTRACT Digital watermarking can be used as an important tool for the security and copyright protection of digital multimedia content. The present paper explores its applications as a quality indicator of a watermarked medical image when subjected to 

End-to-end image quality assessment
free download

ABSTRACT An innovative computerized benchmarking approach (US Patent pending Sep 2011) based on extensive application of photometry, geometrical optics, and digital media using a randomized target, for a standard observer to assess the image quality of video 

Quality Assessment of Pixel-Level Image Fusion Using Fuzzy Logic
free download

ABSTRACT Image fusion is to reduce uncertainty and minimize redundancy in the output while maximizing relevant information from two or more images of a scene into a single composite image that is more informative and is more suitable for visual perception or 

MATLAB-based Applications for Image Processing and Image Quality Assessment Part II: Experimental Results
free download

ABSTRACT The paper provides an overview of some possible usage of the software described in the Part I. It contains the real examples of image quality improvement, distortion simulations, objective and subjective quality assessment and other ways of image 

A comparison of instrumental method and computer image analysis in the quality assessment of particular products.
