Ultrasound (US) imaging is widely used in clinical diagnostics as it is an economical, portable, painless, comparatively safe, and non-invasive real-time tool. However, the image quality of US imaging is severely affected by the presence of speckle noise during the acquisition process. It is essential to achieve speckle-free high resolution US imaging for better clinical diagnosis. In this paper,...
Provisioning of quality of service (QoS) is a key issue in wireless communication systems. Owing to the fact that QoS requirements are not very strict for all traffic types, more calls of higher priority traffic classes can be accommodated by blocking a slightly greater number of calls of lower priority traffic classes. Diverse types of high data rate traffic are supported by existing wireless communication...
Speckle noise is a major shortcoming of any type of ultrasound imaging. Hence, speckle reduction is vital in providing a better clinical diagnosis. The key objective of any speckle reduction algorithm is to attain a speckle free image, whilst preserving the important anatomical features. In this paper, we introduce a nonlinear multi-scale complex wavelet diffusion based algorithm for speckle reduction...
LED-ID wireless communication channel suffers from much impairment such as shadowing, rapid movement of reader in the home environment. In a LED-ID network environment, multiple propagation paths often exist from a Tag to a reader due to scattering by different objects. Signal copies following different paths can undergo different attenuation, distortions, delays and phase shifts. So, this is necessary...
Path mapping and finding the desired path for a mobile cleaning robot in order to perform cleaning efficiently is a difficult task. Moreover, in complex indoor environments, avoiding collision with other furniture or equipment is a big problem for mobile cleaning robot. In the case wireless control link should be robust for accurate moving along the desired path. But wireless radio frequency is experienced...
Due to limited resources in wireless communication, an effective resource allocation mechanism is needed to optimize utilization by reducing blocking probability and dropped call rates. When different users with different priorities use the same network resource, utilization of the resource according to the priority is important. This idea, along with multi-color optical channels can be used in the...
