Speckle reduction is an important pre-processing stage for ultrasound medical image processing. In this paper, an adaptive fuzzy logic approach for speckle noise reduction in ultrasound images is presented. In the proposed method, adaptiveness is incorporated at two levels. In the first level, applying fuzzy logic on the coefficients of variation computed(More)
The simultaneous transmission of data by more than one transmitter leads to interference in the destination. Though this can be overcome by introducing cooperative communication , still the SNR performance is poor. In this paper, Dual Beam Array (DBA) is considered to reduce interference in the place of two single beam arrays. The Dual Beam Array has the(More)
Visual Cryptography Scheme (VCS) is a cryptographic technique which can hide image based secrets. Even though VCS has the major advantage that the decoding can be done with the help of Human Visual System (HVS), yet it does not provide sufficient reconstruction quality. Hence, Two in One Image Secret Sharing Scheme (TiOISSS) is used which provides two(More)
