New display principles aim at supreme image quality. The temporal aspects of these devices sometimes remain underexposed in the literature, and the paper presents an overview of new artifacts and possible remedies with signal processing.

We describe the implementation of an environment for Gesturally-Realized Audio, Speech and Song Performance (GRASSP), which includes a glove-based interface, a mapping/training interface, and a collection of Max/MSP/Jitter bpatchers that allow the user to improvise speech, song, sound synthesis, sound processing, sound localization, and video processing. The mapping/training interface provides ...

Wavelet transformation is one of the most practical mathematical transformations in the field of image processing, especially image and signal processing. Depending on the nature of the multiresolution analysis, Wavelet transformation become more accessible and powerful tools. In this paper, we refer to the mathematical foundations of this transformation.   Introduction: The...

Quality assessment plays a very important role in almost all aspects of multimedia signal processing such as acquisition, coding, display, processing etc. Several objective quality metrics have been proposed for images, but video quality assessment has received relatively little attention. Most of the video quality metrics in the literature are simple extensions of metrics for images. In this p...
