The overwhelming proliferation of digital images on media sharing webs have triggered the requirement of effective tools to retrieve images of interest using semantic concepts. Due to the semantic gap between low-level visual features and high-level semantic concepts of an image, however, the performances of many existing automatic image annotation algorithms are not so satisfactory. In this paper,...
The overwhelming amounts of digital images on the Web and personal computers have triggered the requirement of an effective tool to classify each image into appropriate semantic category based on the image content has become an increasingly difficult and laborious task. To deal with this issue, we propose a novel multi-view semi-supervised learning framework to improve the prediction performance of...
In this paper, we incorporate script into movie content analysis and present a novel movie abstraction approach via the progress of storyline, which is validated by film production theory that film actually catches audiences' attention is the storyline. We first segment scenes by analysis and alignment of script and movie. Then we conduct storyline analysis based on the content attention analysis...
Automatic kinship verification methods are conventionally based on facial appearance. In contrast to all published material, in this paper, we explore the use of facial expression dynamics and spatio-temporal features for kinship verification from smile videos. It is shown that the combined use of dynamic and spatio-temporal features extracted from spontaneous smiles significantly improves the state...
Gender information is a distinctive and the most important property in a speech. Determination of this information from a speech signal is a substantial subject. Gender information used for various purposes in many applications, provides the less error rate by defining the gender-dependent speech/speaker models. In this study, a system determining the gender of a speaker with no dependency from a...
Wireless Multimedia Sensor Networks (WMSNs) are considered as one of the most prominent infrastructures for human-centric multimedia applications due to the wide availability of low-cost hardware such as microphones and CMOS cameras. By virtue of the energy limitations on sensor nodes alongside the explicit highly demanding bandwidth requirements of real-time multimedia applications, these particular...
In this work, we share our experience and knowledge about integration of public service telephone network (PSTN) and IP multi-media systems (IMS). For this purpose, the enhancements and innovations realized by the Netas on access gateway control function (AGCF) solution that enables the integration of IMS with PSTN are presented.
In this paper, it is investigated the processes for automatic identification of the targets without personnel intervention in wireless multimedia sensor networks. Methods to extract the features of the object from the multimedia data and to classify the target type based on the extracted features are proposed within the scope of this study. The success of the proposed methods are tested by implementing...
Wireless Sensor Network implementations move toward multimedia applications which necessitate more energy consumption every other day. Special sensor networks designed primarily for the delivery of multimedia content are called Wireless Multimedia Sensor Networks. In these networks, deployed nodes may change their places with or without user requirement which results in a non-uniform distribution...
Technological developments and increases of the copyright infringements have led a demand on developing automatic video copy detection systems. Generally, for this task, even if visual local descriptors are preferred, descriptors should be indexed according to make an effective search. In this work, performance of three indexing methods which are defined in literature is compared for video copy detection...
Identification and classification of music signals provide solutions for multi-media applications including categorized data sharing over the web. The mathematical analysis of music requires features for discriminating; East-West; Turkish-Arab-Chinese-Indian; blues-jazz-classical music etc. The widely used twelve-tone equal temperament (12-TET) interval system for the classical music and the just...
Brief episodes of network faults and performance issues adversely affect the user Quality of Experience (QoE). Besides damaging the current opinions of users, these events may also shape user's future perception of the service. Therefore, it is important to quantify the impact of such events on QoE over time. In this paper, we present our findings on the temporal aspects of user feedback to disturbances...
This study investigates the metrics for spatial audio quality of experience (QoE) prediction, particularly considering the existence of video whose viewpoint may not match that of the auditory scene. Subjective tests were conducted for 5.1-channel audio quality evaluation following a previously developed testing and prediction methodology, with the addition of accompanying video cues and with the...
Numerous real-time applications are currently deployed over mobile networks — ranging from multimedia streaming, to real-time online games, to video conferences/chat, to real-time stock exchanges, etc. Supporting such applications is challenging because they have very stringent Quality of Service (QoS) requirements in terms of both throughput and delay. To address this challenge, in this paper, we...
E-Learning becomes widely spread in the past few years because it enables learner to participate in anytime, anyplace personalized training. Designing rich E-Learning environment is an important factor to enhancing the effectiveness of web based education. Therefore the necessity of evaluating the web based E-Learning content is arising. The evaluation of E-Learning content is beneficial for learner...
Teaching mathematics has been a complex issue for educators as well as learners. Same is the condition for the hearing impaired learners. Multimedia can be a big facilitator in order to render simpler and effective learning methods in the field of teaching mathematics to the hearing impaired students. The guidelines of United Nations Convention of Rights of Persons with Disabilities (UNCRPD, 2007),...
This research makes innovative use of technology to enhance students' learning experiences in Project Work, by providing interaction through technology to make individual and group thinking more visible. Technology has evolved significantly, which provides opportunities to test new methods of teaching. The idea is to use technology creatively to deconstruct and redefine the classroom, in order to...
How can animation curriculum be successfully integrated into exhibits in primary school? In this study, we seek the position of animation education on multimedia learning, introduce the exhibit mode of animation curriculum and summarize our program of the research. There were K3 students who were never given animation lessons participating in the experiment. We adopted pre-experimental design as our...
The next computer technology revolution prompted by the birth of the Internet of Things (IoT) without a doubt is going to impact health services, particularly eHealth. This paper introduces a formal model integrating IoT and eHealth under the umbrella of service science. The service science component assures that innovative and commerce aspects of a new service denoted SSME/IoT/eHealth is at least...
Music teachers in secondary schools are facing a great challenge when attempting to successfully engage pupils in classical music appreciation. The distance e-learning sector has for a long time neglected to address the specific needs of teaching and learning music. This paper describes the use of social multimedia technologies to engage pupils in classical music appreciation. The approach relies...
