Research ArticleOpen accessPhrase in the titleAN INFORMATION-THEORETIC IMAGE QUALITY MEASURE: COMPARISON WITH STATISTICAL SIMILARITYAsmhan Flieh Hassan, Dong Cai-lin, Zahir M. HussainWe present an information-theoretic approach for structural similarity for assessing gray scale image quality. The structural similarity measure SSIM, proposed in 2004, has been successflly used and verfied. SSIM is based on statistical similarity between the two images. However, SSIM can produce confusing results in some cases where it may give a non-trivial amount of similarity for two different images. … …Journal of Computer Science, Vol. 10, Issue 11 · 17 Dec 2014 · 8,776 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAN IMPROVEMENT OF STRUCTURAL SIMILARITY INDEX FOR IMAGE QUALITY ASSESSMENTEmna Chebbi, Faouzi Benzarti, Hamid AmiriThe image quality assessment has been widely used in image processing. Several researches have been developed and carried considering the Human Visual System (HVS). Under the hypothesis that human visual perception is extremely adapted to retrieve structural information from a scene, the SSIM index is the most widely used in this area, which leads to a better correlation with HVS. … …Journal of Computer Science, Vol. 10, Issue 2 · 21 Nov 2013 · 7,419 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Novel Image Component Transmission Approach to Improve Image Quality and Energy Efficiency in Wireless Sensor NetworksWei Wang, Dongming Peng, Honggang Wang, Hamid SharifDue to resource constraints, digital image transmissions are a significant challenge for image sensor based Wireless Sensor Networks (WSN). In this paper, we propose a novel robust and energy-efficient scheme, called Image Component Transmission (ICT) in WSN by providing various levels of reliability during image transmissions. Different components in the embedded wavelet image bit stream are considered and essential components … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 7,247 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEnhancing Brain MR Image Quality Using CNN With Best Denoising Modality for Improved Diagnosis of Abnormality: An AppraisalKavery Verma, Subodh Srivastava, Ritesh Kumar MishraDigital medical images acquired from the brain are highly susceptible to noise, which causes significant challenges for radiologists to identify abnormalities in a precise manner. Noise interference hampers both diagnostic accuracy and the interpretation of underlying abnormalities, potentially leading to flaw conclusions. Magnetic Resonance (MR) imaging is the most preferred digital imaging technique for brain abnormality detection. To achieve precise … …Journal of Computer Science, Vol. 22, Issue 3 · 26 Mar 2026 · 1,462 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNOVEL IMAGE-DEPENDENT QUALITY ASSESSMENT MEASURESZahir M. Hussain, Asaad Noori HashimThe image is a 2D signal whose pixels are highly correlated in a 2D manner. Hence, using pixel by pixel error what we called previously Mean-Square Error, (MSE) is not an efficient way to compare two similar images (e.g., an original image and a compressed version of it). Due to this correlation, image comparison needs a correlative quality measure. It … …Journal of Computer Science, Vol. 10, Issue 8 · 27 Feb 2014 · 7,434 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Plastic Wedges on Whole Foot Radiograph in Anteroposterior and Oblique PositionsPoe Lorlorm, Winit Choiprasert, Montree Tungjai, Suchart KothanThe whole foot radiography may be taken twice with different exposure parameters. It produces two images in two radiation exposures; one is the metatarsal view of the phalange and the other is a tarsal view. The aim of this study was to study the effects of plastic wedges on whole foot radiography with one radiation exposure. The plastic wedge was … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 27 Apr 2017 · 7,591 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Discussion of Different Noises and FiltersP.N. Sundararajan, S. Sasi KumarIn digital image processing, noise acquisition and noise removal is required to enhance the quality of an image and during transmission variety of noise that affects the quality of the image. The major intension of filtering or de-noising the image is to reconstruct the detail of master image as much as possible. The metrics of the image noise removal trouble … …American Journal of Applied Sciences, Vol. 11, Issue 12 · 3 Jan 2015 · 5,973 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMODELING THE EFFECTIVENESS OF THE CORPORATE IDENTITY MIX IN PERCEIVED QUALITY AND CUSTOMER-RELATED BRAND EQUITY WITH INTERPRETIVE STRUCTURAL EQUATIONS AND MICMAC ANALYSISMahsa Pishdar, Mohammad Reza Seyyed Hashemi Toloun, Fereshteh Farzianpour, Morteza RezaeiaslThis study aims to identify the relation between corporate identity mix, perceived quality on customers’ behalf and customer-centric brand equity. A review of the available literature within this scope resulted in making a primary model which represents that the corporate identity mix has an effect upon the perceived quality and brand equity by some variables such as corporate image and … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 29 Jan 2014 · 7,160 accessesView PDFCite

The CCD Camera is used to capture the two dimensional flame images. The features such as images, average intensity, area, brightness and orientation etc., of the … …American Journal of Applied Sciences, Vol. 15, Issue 1 · 7 Feb 2018 · 7,552 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA High Secure and Robust Image Steganography Using Dual Wavelet and Blending ModelR. Bhavani, Prabakaran GanesanSteganography is an ability of concealing information inside the cover in such a way it looks like simple cover though it has concealed information. There are many techniques to carry out steganography on electronic media, most especially audio and image files. In this method, we proposed a high secure steganography scheme hiding a 256×256 size gray secret image into a … …Journal of Computer Science, Vol. 9, Issue 3 · 12 Apr 2013 · 6,429 accessesView PDFCite
