Artificial neural network (ANN) has application in communication engineering in diverse areas such as channel equalization, channel modeling, error control code because of its capability of nonlinear processing, adaptability, and parallel processing. On the other hand, wavelet transform (WT) with both the time and the frequency resolution provides the exact representation of signal in both doma...

The papers in this special issue focus on deep learning for image/video restoration and compression. huge success of deep-learning–based approaches computer vision has inspired research learned solutions to classic processing problems, such as denoising, deblurring, dehazing, deraining, super-resolution (SR), Hence, learning-based methods have emerged a promising nonlinear signal-processing fra...

The Centre for Digital Video Processing at Dublin City University conducts concentrated research and development in the area of digital video management. The current stage of development is demonstrated on our Webbased digital video system called Físchlár [1], which provides for efficient recording, analysing, browsing and viewing of digitally captured television programmes.

In digital image processing noise removal or noise filtering plays an important role, because for meaningful and useful processing images should not be corrupted by noises. In recent years, high quality televisions have become very popular but noise often affects TV broadcasts. Impulse noise corrupts the video during transmission and acquisition of signals. A number of denoising techniques have...

Clock synchronization is a critical component in wireless sensor networks, as it provides a common time frame to different nodes. It supports functions such as fusing voice and video data from different sensor nodes, time-based channel sharing, and sleep wake-up scheduling, etc. Early studies on clock synchronization for wireless sensor networks mainly focus on protocol design. However, clock s...

A fast Discrete Cosine Transform (DCT) algorithm is introduced that can be of particular interest in image processing. The main features of the algorithm are regularity of the graph and very low arithmetic complexity. The 16-point version of the algorithm requires only 32 multiplications and 81 additions. The computational core of the algorithm consists of only 17 nontrivial multiplications, th...

tomization and advanced feature updates. Original equipment manufacturers (OEMs) often need to use the same system platform across a range of products that are tailored for specific markets; or they need to combine different applications in the same system, such as a security camera with object recognition, or an IPTV set-top box (STB) with integrated video phone or digital media adapter capabi...
