Publikováno v: EAI Endorsed Transactions on Pervasive Health and Technology, Vol 2, Iss 8 (2016)

This paper presents a novel study of logarithmic discrete wavelet transform (DWT) for medical image compression. It proposes a new technique to compute the DWT using the logarithmic number system (LNS) instead of floating point arithmetic. It investi
