Research ArticleOpen accessEvery word in the titleIndexing Medical Images Using the Wavelet Transform: Application to Retinal ImagesSouad Meziane Tani, Abdelhafid BessaidContent-Based Image Retrieval Systems (CBIR) provide effective support to the doctor to find relevant images using their visual content. Current medical systems are unable to provide accurate and precise results. To solve this problem, effective indexing algorithms are required to extract the contents of the images. In this study, the method of indexing image from the energy coefficients of the … …Current Research in Bioinformatics, Vol. 2, Issue 2 · 1 Jul 2014 · 6,698 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBRAIN TUMOR CLASSIFICATION BASED ON CLUSTERED DISCRETE COSINE TRANSFORM IN COMPRESSED DOMAINV. Anitha, S. MurugavalliThis study presents a novel method to classify the brain tumors by means of efficient and integrated methods so as to increase the classification accuracy. In conventional systems, the problem being the same to extract the feature sets from the database and classify tumors based on the features sets. The main idea in plethora of earlier researches related to any … …Journal of Computer Science, Vol. 10, Issue 10 · 6 May 2014 · 7,537 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCLASSIFICATION OF MICROCALCIFICATION BASED ON WAVE ATOM TRANSFORMA. Rajesh, Mohan EllappanBreast cancer is a serious problem for women in the world. It is the most common form of cancer diagnosed in woman, with one in nine women expected to be diagnosed with some form of cancer in their life-time. It is second only to lung cancer in cancer related deaths. Statistics shows that the case of breast cancer in the … …Journal of Computer Science, Vol. 10, Issue 8 · 5 Apr 2014 · 6,523 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NOVELTY APPROACH OF SPATIAL CO-OCCURRENCE AND DISCRETE SHEARLET TRANSFORM BASED TEXTURE CLASSIFICATION USING LPBOOSTING CLASSIFIERC. Vivek, S. AudithanRecently, the research towards Brodatz database for texture classification done at considerable amount of study has been published, the effective classification are vulnerable towards for training and test sets. This study presents the novel texture classification method based on feature descriptor, called spatial co-occurrence with discrete shearlet transformation through the LPboosting classification. It can be considered as a frame through … …Journal of Computer Science, Vol. 10, Issue 5 · 11 Jan 2014 · 6,608 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePOWER QUALITY DIAGNOSIS IN DISTRIBUTION NETWORK USING WAVELET TRANSFORMH. H. Goh, H. L. Ting, Q. S. Chua et al.Power quality is one of the most concerns to the electric power suppliers, equipment manufacturers and the users of various electrical and electronic equipments. This paper presents the use of a continuous wavelet transform to detect and analyse voltage sags and swells. Characteristics which include duration and magnitude of the investigated signals are measured. Unlike other approaches where the detection … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 26 Dec 2013 · 7,064 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCONTENT BASED BATIK IMAGE CLASSIFICATION USING WAVELET TRANSFORM AND FUZZY NEURAL NETWORKAbdul Haris RangkutiIn this paper we introduce the content-based image classification using wavelet transform with Daubechies type 2 level 2 to process the characteristic texture consisting of standard deviation, mean and energy as Input variables, using the method of Fuzzy Neural Network (FNN). All the input value will be processed using fuzzyfication with 5 categories namely Very Low (VL), Low (L), Medium … …Journal of Computer Science, Vol. 10, Issue 4 · 19 Dec 2013 · 6,691 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAREA EFFICIENT DISTRIBUTED ARITHMETIC DISCRETE COSINE TRANSFORM USING MODIFIED WALLACE TREE MULTIPLIERR. P. Meenaakshi Sundari, R. Anita, V. VenkateshwaranIn this study by using the modified Wallace tree multiplier, an error compensated adder tree is constructed in order to round off truncation errors and to obtain high through put discrete cosine transform design. Peak Signal to Noise Ratio (PSNR) is met efficiently since modified Wallace Tree method is an efficient, hardware implementable digital circuit that multiplies two integers resulting … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 19 Dec 2013 · 7,335 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleINDEPENDENT COMPONENT ANALYSIS AND DISCRETE WAVELET TRANSFORM FOR ARTIFACT REMOVAL IN BIOMEDICAL SIGNAL PROCESSINGSalvatore Calcagno, Fabio La Foresta, Mario VersaciRecent works have shown that artifact removal in biomedical signals can be performed by using Discrete Wavelet Transform (DWT) or Independent Component Analysis (ICA). It results often very difficult to remove some artifacts because they could be superimposed on the recordings and they could corrupt the signals in the frequency domain. The two conditions could compromise the performance of both … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 27 Nov 2013 · 7,856 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGAUSSIAN MIXTURE MODEL BASED CLASSIFICATION OF MICROCALCIFICATION IN MAMMOGRAMS USING DYADIC WAVELET TRANSFORMSuman Mishra, Hariharan RanganathanBreast cancer is a serious health related issue for women in the world. Cancer detected at premature stages has a higher probability of being cured, whereas at advanced stages chances of survival are bleak. Screening programs aid in detecting potential breast cancer at early stages of the disease. Among the various screening programs, mammography is the proven standard for screening … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,873 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Image Dithering Via Tchebichef Moment TransformNur Azman Abu, Ferda Ernawan, Nanna SuryanaMany image display applications and printing devices allow only limited number of colours. They have limited computational power and storage to produce high quality outputs on high bit-depth colour image. A dithering technique is called for here in order to improve the perceptual visual quality of the limited bit-depth images. A dithered image is represented by a natural colour in … …Journal of Computer Science, Vol. 9, Issue 7 · 11 Jun 2013 · 7,350 accessesView PDFCite
