چکیده

Transmodality is the partitioning of an image into regions that are expected to present a better entropy using different coding schemes, depending on their structural density, at constant bandwidth. In this paper we present the transmodality of video stream. Our contribution is a transmoder module that includes various different optimized video codecs and implements the concept of transmodality on a set of video streams. We evaluate our proposal with different kinds of video (in content term), and our algorithm shows comprehensive results by saving up to 8% of bandwidth for the same PSNR in comparison with the state-of-the-art video

An Ontological Analysis about Dynamic Composition of Abstract Fonts in Interactive Video Art Installation

An interactive video installation using an abstract font as visual elements is explained. The interactive abstract characters respond to viewers by varying their sizes while moving about in the video space, as algorithmically specified by a computer. This results in interactive and dynamic compositions of multiple abstract characters. In this paper, we study the characteristics of such dynamic ...

A Novel Approach to Background Subtraction Using Visual Saliency Map

Generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. Using visual saliency map for modelling gives important information for understanding in many applications. In this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. The proposed technique i...

Adaptive Spectral Separation Two Layer Coding with Error Concealment for Cell Loss Resilience

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

Adaptive Audio-visual Speech Recognition in the Presence of Audio and Video Distortions

Audio-visual speech recognition leads to significant improvements compared to pure audio recognition especially when the audio signal is corrupted by noise. In this article we investigate the consequences of additional degradations in the video signal on the audio-visual recognition process.. We degrade the images with noise, a JPEG compression, and errors in the localization of the mouth regio...
