Stereoscopic imaging technology has aroused a great concern recently due to the increasingly wide range of stereoscopic applications. Stereoscopic image quality assessment is of vital importance to evaluate the performance of three-dimensional video (3DV) systems. However, stereoscopic image quality assessment methods are very scarce presently. In the paper, according to human visual sensitivit...

--Image Quality assessment plays an important role in various image processing applications. It is still an active area of research. A great deal of effort has been made in recent years to develop objective image quality metrics that correlate well with perceived human quality measurement or subjective methods. Most full reference(FR) technique were derived based on pixel to pixel error such as...

Background: Patient radiation doses from computed tomography (CT) are increasing due to the number of CT examinations performed every day. The aim of this study was assess and evaluate patient radiation doses for adult’s common CT examinations to derive local diagnostic guidance levels for common CT examinations. Materials and Methods: Volume and weighted computed tomography dose index (C...

In most practical situations, images and videos can neither be compressed nor transmitted without introducing distortions that will eventually be perceived by a human observer. Vice versa, most applications of image and video restoration techniques, such as inpainting or denoising, aim to enhance the quality of experience of human viewers. Correctly predicting the similarity of an image with an...

A C-arm CT system offers the possibility to acquire 2-D high-resolution X-ray images of the patient from different views. These projections can be used for 3-D imaging. Anatomical three-dimensional imaging holds great potential to improve cardiac interventions. However, the image acquisition using a C-arm CT system takes several seconds. A standard FDK reconstruction using all acquired projecti...

introduction spect projections are contaminated by scatter radiation, resulting in reduced image contrast and quantitative errors. backscatter constitutes a major part of the scatter contamination in lower energy windows. the current study is an evaluation of the effect of backscatter material on fwhm and image quality investigated by monte carlo simulation. materials and methods simind program...

Full-reference image quality assessment methods seek to measure visual similarity between two images (in practice, one original and the other its altered version). It has been established that traditional methods, such as Mean Square Error and Peak Signal-to-Noise Ratio poorly mimic the human visual system and much of the recent research in image quality assessment has been directed toward deve...

⎯Recently, an edge adaptive image steganographic method based on least significant bit (LSB) matching revisited (EA-LSBMR) has been proposed, which holds good visual quality and proper security under appropriate embedding rates. However, from the extensive experiments to EA-LSBMR, we find that the discrete Fourier transform (DFT) spectrum of pixelpairs differences histogram still reveals the pr...

This paper presents transmission and reception of grey scale image through Rayleigh fading channel. Grey scale image is made up of pixel values. These pixel values are represented by decimal values. For transmission these pixel values are obtained using MATLAB and converted into binary bits. Grey Scale image is transmitted through different systems. Firstly it is transmitted through Alamouti Sp...
