Audio-visual interaction in multimedia communication

Audio-visual interaction in multimedia communication

Proceedings of the 1997 IEEE International conference on Acoustics, Speech, and Signal processing, ICASSP. Part 1 (of 5)

作者： Chen, Tsuhan Rao, Ram R. AT&T Lab - Research Holmdel United States

To many people, the word `multimedia' simply means the combination of various forms of information: text, speech, music, images, graphics and video. What is often overlooked is the interaction among these forms. In this paper, we will present our recent results in exploiting the audio-visual interaction that is very significant in multimedia communication. The applications include lip synchronization, joint audio-video coding, and person verification. We will present the enabling technologies, including audio-to-visual mapping and facial image analysis, for these applications. Our results show that the joint processing of audio and video provides advantages that are not available when audio and video are studied separately.

visual cryptography has a good application prospect in halftone information hiding and anti-counterfeiting. This paper mainly studies the application of this technology in office partition and window painting, decorative calligraphy and painting, etc. In order to achieve a visual isolation and calligraphy and painting presentation function of information hiding and presentation method. visual encryption, halftone image processing, digital modulation and information coding techniques are applied. visual encryption A and its open-key image B are generated by the algorithm, and then image B is modulated by halftone calligraphy image. The half-tone calligraphy image information is image B. When image A and carrier image B are superimposed together, the compatibility of halftone noise isolation image and half-tone calligraphy image can be realized by position adjustment. The results show that the method achieves good compatibility in information hiding and artistic expression. © 2019 IEEE.

Researchers have increasingly turned to crowdfunding platforms to gain insights into entrepreneurial activity and dynamics. While previous studies have explored various factors influencing crowdfunding success, such as technology, communication, and marketing strategies, the role of visual elements that can be automatically extracted from images has received less attention. This is surprising, considering that crowdfunding platforms emphasize the importance of attention-grabbing and high-resolution images, and previous research has shown that image characteristics can significantly impact product evaluations. Indeed, a comprehensive review of empirical articles (n = 202) utilized Kickstarter data, focusing on the incorporation of visual information in their analyses. Our findings reveal that only 29.70% controlled for the number of images, and less than 12% considered any image details. In this manuscript, we contribute to the existing literature by emphasizing the significance of visual characteristics as essential variables in empirical investigations of crowdfunding success. We review the literature on image processing and its relevance to the business domain, highlighting two types of visual variables: visual counts (number of pictures and number of videos) and image details. Building upon previous work that discussed the role of color, composition, and figure-ground relationships, we introduce visual scene elements that have not yet been explored in crowdfunding, including the number of faces, the number of concepts depicted, and the ease of identifying those concepts. To demonstrate the predictive value of visual counts and image details, we analyze Kickstarter data using flexible machine learning models (Lasso, Ridge, Bayesian additive regression trees, and eXtreme Gradient Boosting). Our results highlight that visual count features are two of the top three predictors of success and highlight the ease at which researchers can incorporate some information abou

This paper presents an analysis of technologies and resources needed for building of a multimodal information kiosk for deaf people. The considered information kiosk will use sign language as main communication means, since it is main language of communication of deaf users. Thus, the sign language synthesis and recognition modules will be main part of the kiosk. Additional modules include lip-reading support for sign language recognition (since sign language is accompanied by lip articulation), touch screen input, and graphical user interface. To design and build the mentioned modules, large amounts of data are needed for training, especially in the case of recognition modules. The information kiosk is intended for use for provididng/gathering information to/from deaf users, such us train connection or communication with authorities. Copyright © 2008 AVISA.

A novel approach to steady-state visual evoked potential (SSVEP) based brain-computer interface (BCI) is presented in the paper. To minimize possible side effects of the monochromatic light SSVEP-based BCI we propose to utilize chromatic green blue flicker stimuli in higher, comparing to the traditionally used, frequencies. The developed safer SSVEP responses are processed an classified with features drawn from EEG power spectra. Results obtained from healthy users support the research hypothesis of the chromatic and higher frequency SSVEP. The feasibility of proposed method is evaluated in a comparison of monochromatic versus chromatic SSVEP responses. We also present preliminary results with empirical mode decomposition (EMD) adaptive filtering which resulted with improved classification accuracies.

Design method is an important part of design, and it is an important product of academic and educational research practice. This paper discusses different fields of visual design and their methodological issues, based on the definition of visual communication design, WOS and a search of relevant literature on the Internet, with the aim of understanding the essential properties of visual communication activities from a methodological stratification perspective and clarifying the norms of different disciplines involved in visual communication. The objectives, content, processing, and output of two types of visual design activities with purpose and means are analyzed in terms of design process, conceptual framework of visual representation, and qualitative and quantitative aspects. As an interdisciplinary design discipline, visual design is essentially a comprehensive activity of information dissemination that occurs in a variety of scenarios, including business, education, and science. It is necessary to keep the boundary, clarify the ideographic and stylistic characteristics of visual design, and improve the ontological quality of visual design profession, but it is also necessary to cross the boundary on the basis of keeping the boundary, so as to better cultivate visual ability, promote the transformation of visual design methods in other fields, and improve the disciplinary growth of the profession in the new era. © 2021 ACM.

This research aims to let people know their hierarchy of prolonged distractions starting from the most distracting to the least distracting factors while driving a car. In order to do this, an HTML5 game that simulated a car drive with numerous distractions, which include both audio and visual distractions, was created. The player of the game needs to wear an EEG device, Neurosky, for his or her Beta waves to be detected and collected. The collected Beta waves are then passed to the HTML5 game for processing. This process correlated prolonged distractions with their respective hierarchical position for the player. Once the player receives his/her respective hierarchy of prolonged distractions, he/she will be able to improve and even learn to avoid certain distractions.
