Hospitals and medical centers produce an enormous amount of digital medical images
every day, which are used for different purposes such as surgical and diagnostic plans. The …

New wireless physical-layer designs are the key to improving wireless network performance.
Adopting these new designs, however, requires modifications on wireless hardware and is …

The heart of the current wireless communication systems (including 5G) is the Fourier
transform‐based orthogonal frequency division multiplex (OFDM). Over time, a lot of …

In this paper, we present a multiple description video coding algorithm based on error-
resilient and error concealment set partitioning in hierarchical trees (ERC-SPIHT). In this …

If a system for lossless compression of images applies a decorrelation step, this step must
map integer input values to integer output values. This can be achieved, for example, using …

In this paper we propose an energy efficient image transmission strategy for wireless sensor
networks, which combines wavelet-based image decomposition and cooperative …

A novel data structure is proposed for magnitude-ordering 3-D wavelet transform
coefficients. This data structure consists of temporal 1-D orientation trees followed by spatial …

Robust and secure transmission strategy for high-quality image through wireless networks is
considered a great challenge. However, majority of encrypted image transmission schemes …

To meet the requirements of communication networks and storage capacity, medical images
are required to be compressed before storage and transmission. Therefore different …

The goal of this thesis is to propose a novel video coding architecture which is inspired by
the mammalian visual system and the retina. If one sees the retina as a machine which …
