From the perspective of teaching practical application, the principles and objectives of the design of multiwindow multimedia teaching platform are discussed. Based on C++ and software dynamic integration technology, the key technologies of multiwindow multimedia teaching platform implementation are presented and stated in detail.
The rapid development of economic society puts forward higher requirements for English talents. Currently, the English education in colleges and universities stays in the onefold teaching mode, the teaching efficiency is low, and the students do not have good English comprehensive application ability. Based on the network multimedia technology, college English teaching mode of constructivism can be...
Delay has been found as one of the most crucial factors determining the Quality of Experience (QoE) in synchronous video-mediated communication. The effect has been extensively studied for dyadic conversations and recently the study of small group communications has become the focus of the research community. Contrary to dyads, in which the delay is symmetrically perceived, this is not the case for...
In China, bilingual teaching is a new issue occurred during the period of social and economic rapid development accompanied with its raising global position. In the bilingual teaching experiment process, new methods, such as introducing bilingual textbook, step by step and learning new knowledge on the basis of reviewing the material learned, were adopted to improve students' English proficiency level...
Mobile devices are making a giant stride in both the educational and industrial arena. They tend to enhance the efficiency and effectiveness of learning by providing a contextual and ubiquitous access. Traditional form of learning does not adequately cater for active learners because they always want to learn by doing. In this paper we detailed the analysis, design and implementation of multimedia...
With the development of information technology and wide application of all walks of life got rapid development in the field of network information. Using multimedia teaching has become a mainstream trend of the teaching. However, multimedia teaching means in the process of using and implementation also has certain problem. The emergence of cloud computing for building open, safe and efficient platform...
In the cultivation of Chinese education scheme in modern vocational colleges, not only includes the demand for educators but also Chinese educators that have higher education quality. Education concept and methods also began to develop in the direction of informationization, diversification, and emotionalization. Higher vocational education is a type of education; it plays a very important role in...
We propose a variable multi-pulse pulse-position-modulation (VMPPM) system with a dimming control that combines the use of pseudo-orthogonal codes and MPPM. In VMPPM, r slots are selected from n MPPM slots and codes for data are generated in each selected r slot according to source data equation [bit/frame]. This enables VMPPM to achieve a higher data-transmission rate than the conventional variable...
In this paper, all bits of adjacency pixels are linked with a XOR operator. If the XOR value of a pixel is not compatible with its corresponding secret bit, the way to change the XOR value of a pixel can modify not only the pixel itself, but also its adjacency pixels instead. According to this concept, the proposed embedding algorithm is to find the least quantity of pixel modifications such that...
Reversible data hiding has emerged in recent years, and it has the fundamental requirement of reversibility. For reversible data hiding, secret information is embedded into original image with devised algorithms, and the marked image should be delivered to the decoder without any damage. For decoding, both the embedded secret and original image should be recovered perfectly. With these characteristics,...
Background subtraction is one of important fundamental steps in many image processing applications such as object recognition, detection, tracking, human behavior analysis in video surveillance systems, etc. So the background subtraction method must be efficiency, that is saving time and space and have a good performance. In order to achieve this aim, a new background subtraction method is proposed...
Image retargeting means to change the aspect ratio and resolution of an image in order to display it on different devices. During retargeting, how to keep significant image areas from obvious distortion is the main consideration. The seam carving method handles the challenge by recursively removing pixel seam with minimal cost. Though it can generate convincing results, the computation needed to find...
In this study, we have demonstrated an integrated approach to produce a digital storytelling for a rural village by an e-Tourism Service. The location-based Show Taiwan e-Tourism Service has a salient feature of making thematic, interactive multimedia stories by using photographs, audios and video clips. For the practical purpose, we have invited the local experts to join and to share the domain knowledge...
The network distance education is a new form of further education based on computer information technology, its advantages lie in breaking the limits of time and space, besides stimulating students the initiative of learning. However, it influenced by traditional academic education, so the advantages of the above model don't get fully exerted. The text analyzes from these above problems, it based...
Traditional video sequences make use of both visual images and audio tracks which are perceived by human eyes and ears, respectively. In order to present better ultra-reality virtual experience, the comprehensive human sensations (e.g. olfaction, haptic, gustatory, etc) needed to be exploited. In this paper, a multiple sensorial media (mulsemedia) delivery system is introduced to deliver multimedia...
We investigated on an efficient masker for speech privacy protection. Previously, we proposed a speaker-dependent (SD) masker created from speech of the masked speaker. This masker decreased the speech intelligibility to a much lower level than conventional babble maskers. However, this masker needs to be prepared for each potential speaker, and may be expensive to create and maintain. We also investigated...
In recent years, several data hiding techniques have been developed. Hsiao and Chang proposed a data hiding scheme in 2011. This approach utilizes just noticeable distortion (JND) techniques to determine whether a pixel can be included in hidden information based on its value, but the calculation procedure is very complex. Therefore, our research seeks to improve Hsiao and Chang's method through the...
This article presents the initiatives and user-centered design activities undertaken by the Faculty of electrical engineering and Faculty of computer science within the largest Slovenian university, the University of Ljubljana to increase the interest in technical studies and especially in the newly introduced interdisciplinary university study program Multimedia. A special attention was devoted to...
For years students and educators alike expressed frustration with the teaching and learning of the subject of electromagnetics. Microwave application areas, high frequency electronics, fast computers, and wireless-based technologies continued to grow and expand, yet concepts of electromagnetics, so familiar to practitioners, continued to be mysterious and challenging to learn for beginners. The Antennas...
Cross-media retrieval is a challenging problem in multimedia retrieval area. In the real-world, many applications involve multi-modal data, e.g., web pages containing both images and texts. How to utilize the intrinsic intra-modality and inter-modality similarity to learn the appropriate relationships of the data objects and provide efficient search across different modalities is the core of cross-media...
