In this paper, we analyze the influence of temporal asynchrony on the subjective quality of stereoscopic video. Based on our recently created 3D video database, different levels of asynchrony were simulated and a comprehensive subjective test was conducted to determine the associated degradations in quality of experience. Furthermore, we developed a method to detect asynchrony between left and right...
Content-based video retrieval has become a very active research area in the last decade due to the increasing number of video content shared on social networks such as YouTube and DailyMotion. While most of the content-based video retrieval approaches employ low-level visual features for global analysis of the video, this paper proposes an object-based retrieval method as an alternative. The goal...
This paper presents a novel training algorithm of hidden Markov models (HMMs) for visual speech recognition based on a modified simulated annealing (SA) algorithm, hybrid simulated annealing, where SA is combined with a local optimization technique to improve the convergence speed and the solution quality. While the popular training method of HMMs, the expectation-maximization (EM) algorithm, only...
