Research ArticleOpen accessIn the keywordsAn 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
