ABSTRACT: For analyzing non-linear and non-stationary signals Empirical Mode Decomposition (EMD) is introduced as an adaptive method like wavelet packet best basis decomposition. Huang et. al introduced the empirical mode decomposition (EMD) in signal processing in 1998. In this communication we investigated the performance of video denoising using bi-dimensional EMD along with wavelet threshol...

objective: it has been recognized that sleep has an important effect on emotion processing. the aim ‎of this study was to investigate the effect of previous night sleep duration on autonomic ‎responses to musical stimuli in different emotional contexts.‎ method: a frequency based measure of gsr, pr and ecg signals were examined in 35 healthy ‎students in three groups of oversleeping, lack of sl...

Visuospatial experience, the prolonged engagement in a demanding visual task, obtained through action video game play enhances several visual and cognitive processes. The underlying mechanisms involved in these processes, however, remain unclear. Here we demonstrate that experience with action video games modulates early sensory processing, resulting in increases sensitivity to salient visual e...

The Multimedia Video Engine is an embedded system for real-time image-processing application The apparatus captures a video signal from an analog source, it processes the data by using a high performance digital signal processor (TMS320C6415), and then displays the results on a graphics monitor. Since several video imaging applications require user interaction, a graphical user interface (GUI) ...

In this paper, we propose an efficient watermarking scheme for H.264/SVC, where the watermarking is performed by using a block-based approach. The embedding process of watermark in the proposed scheme is performed in the encoder of H.264/SVC. The blocks for watermarking embedding are selected by considering both the length of the watermark signal and the size of the input video frame. The water...

Currently, the development of multimedia communication has progressed so rapidly that the video program service has become a requirement for ordinary customers. The quality of experience (QoE) for the visual signal is of the fundamental importance for numerous image and video processing applications, where the goal of video quality assessment (VQA) is to automatically measure the quality of the...
