Research ArticleOpen accessEvery word in the titleEnhancing Digital Images Through Cuckoo Search Algorithm in Combination with Morphological OperationK. Ratna Babu, K. V.N. SunithaThis study presents an image enhancement approach to Cuckoo Search Algorithmin with Morphological Operation. At the present time, in many image processing applications digital images are developed. Machine vision, computer interfaces, manufacturing, compression for storage and more are some of the fields of image processing application. Before using it in any applications the image has to be managed, such processing … …Journal of Computer Science, Vol. 11, Issue 1 · 10 Sep 2014 · 7,455 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA MODIFIED ELLIPTIC CURVE DIGITAL SIGNATURE ALGORITHM FOR PUBLIC VERIFIABILITY WITH DATA DYNAMICS IN CLOUD COMPUTINGD. Sumathi, Ramachandra V. PujeriCloud storage is considered to be the most critical factor in decision making for users as it largely scales down the infrastructure in terms of size, cost and design. Considering factors such as local storage cost, maintenance a single server model can support multiple users on a needed basis. This raises concerns for integrity verification i.e., assuring the correctness of … …Journal of Computer Science, Vol. 10, Issue 10 · 28 Jun 2014 · 6,489 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAN INNOVATIVE MORPHOLOGICAL APPROACH FOR NOISE REMOVAL CUM EDGE DETECTION FOR DIGITIZED PAINTINGSS. P. Karuppiah, S. K. SrivatsaThe older paintings suffer from breaks in the substrate, the paint, or the varnish. When we digitized these paintings, they can be modified using mathematical algorithms and cracks are eliminated so as to maintain the quality. The field of computer vision is concerned with extracting features and information from images in order to make analysis of images easier, so that … …Journal of Computer Science, Vol. 10, Issue 8 · 19 Jun 2014 · 6,705 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleINTELLIGENCE MOBILE AND DIGITAL BROADCASTING TECHNOLOGY TO SUPPORT LEARNING FOR DISABILITIES STUDENTSSettachai Chaisanit, Chiraphorn Chomyim, Samphan ChandeeUsage of mobile digital broadcasting technologies in education is the most important of required technologies to provide main goals in distance education. It offers learning and data accession opportunities to learners notwithstanding time and place. In academic education, it was found that one of the critical problem is the appreciate education tool for disabilities students. Students with special education have … …Journal of Computer Science, Vol. 9, Issue 10 · 18 Sep 2013 · 7,429 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFUZZY TOPOLOGICAL DIGITAL SPACE OF FLAT ELECTROENCEPHALOGRAPHY DURING EPILEPTIC SEIZURESMuhammad Abdy, Tahir AhmadEpileptic seizures are manifestations of epilepsy caused a temporary electrical disturbance in a group of brain cells. Electroencephalography (EEG) is a recording of electrical activity of the brain and it contains valuable information related to the different physiological states of the brain. Flat EEG (fEEG) was developed to compress and analyze information in the brain during epileptic seizures obtained from … …Journal of Mathematics and Statistics, Vol. 9, Issue 3 · 5 Jul 2013 · 7,205 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMass Classification in Digital Mammograms based on Discrete Shearlet TransformJ. Amjath Ali, J. JanetThe most significant health problem in the world is breast cancer and early detection is the key to predict it. Mammography is the most reliable method to diagnose breast cancer at the earliest. The classification of the two most findings in the digital mammograms, micro calcifications and mass are valuable for early detection. Since, the appearance of the masses are … …Journal of Computer Science, Vol. 9, Issue 6 · 1 Jun 2013 · 6,553 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSecond-Order Statistical Approach for Digital Modulation Scheme Classification in Cognitive Radio Using Support Vector Machine and K-Nearest Neighbor ClassifierS. Ravi, R. KannanCognitive radio systems require detection of different signals for communication. In this study, an approach for multiclass signal classification based on second-order statistical feature is proposed. The proposed system is designed to recognize three different digital modulation schemes such as PAM, 32QAM and 64QAM. The signal classification is achieved by extracting the 2nd order cumulants of the real and imaginary … …Journal of Computer Science, Vol. 9, Issue 2 · 11 Apr 2013 · 6,735 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModelling of Digital Assisted Backend Correction Analogue to Digital Converters with Verilog-AGong Yuehong, Luo Min, Ma JianguoProblem statement: Pipelined architecture is considered to be the most suitable for high-speed and high-resolution applications among varies Nyquist Analogue to Digital Converters (ADCs) in nowadays digital signal processing domain. But the pipeline power consumption is growing with the technology scaling.

Research ArticleOpen accessEvery word in the titleDesign and Implementation of an Efficient Software Communications Architecture Core Framework for a Digital Signal Processors PlatformWael A. Murtada, Mohamed M. Zahra, Magdi Fikri et al.Problem statement: The Software Communications Architecture (SCA) was developed to improve software reuse and interoperability in Software Defined Radios (SDR). There had been performance concerns since its conception. Arguably, the majority of the problems and inefficiencies associated with the SCA can be attributed to the assumption of modular distributed platforms relying on General Purpose Processors (GPPs) to perform all signal … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 7,499 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Novel Fidelity Digital Watermarking Based on Adaptively Pixel-Most-Significant-Bit-6 in Spatial Domain Gray Scale Images and RobustMehemed Bashir Aliwa, Tarek El-Ahmady El-Tobely, Mahmood M. Fahmy et al.The digital watermarking technology is a way to apply digital information hiding techniques and prevent malicious and non-malicious attacks to detect hidden information. Problem statement: The problems in digital watermarking is that the three requirements of imperceptibility, capacity and robustness that are must be satisfied but they almost conflict with each other, accordingly there are tradeoff between fidelity and robustness. … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 7,161 accessesView PDFCite
