Research ArticleOpen accessIn the keywordsContent Based Image Retrieval of Ultrasound Liver Diseases Based on Hybrid ApproachR. Suganya, S. RajaramProblem statement: In the past few years, immense improvement was obtained in the field of Content-Based Image Retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted from … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 24 Mar 2012 · 7,643 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Enhanced Approach for Medical Brain Image EnhancementJ. Umamaheswari, G. RadhamaniProblem statement: One of the most common degradations in medical images is their poor contrast quality and noise. The DICOM image consists of speckle (multiplicative noise). While the image is enhanced, the multiplicative noise present in the image is also enhanced. Approach: This study describes the hybrid method to improve the image quality of Digital Imaging and Communications in Medicine … …Journal of Computer Science, Vol. 8, Issue 8 · 27 Jul 2012 · 6,964 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTowards An XML-Based Normalization for Healthcare Data ExchangesI. El Azami, M. M.O. Cherkaoui, C. TahonProblem statement: Most of healthcare data exchanges are textual, poorly structured and often not accessible by clinical professionals. Otherwise, the variety of medical applications and medical standards makes difficult sharing and communicating healthcare data in a highly heterogeneous environment. Approach: XML and related standards (XML schema, XSL) provided an infrastructure that might change the situation. Our aim in this study … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,402 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperiment of Tamper Detection and Recovery Watermarking in Picture Archiving and Communication SystemsSiau-Chuin Liew, Jasni Mohamad ZainProblem statement: Medical images such as x-rays, ultrasounds and Magnetic Resonance Imaging (MRI) plays an important role in helping the physicians to diagnose a disease or body conditions. These images can be tampered with existing image processing tools that is easily available. The usage of security measures such as watermarking can protect the integrity of the images. Numerous watermarking schemes … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,651 accessesView PDF Cite
