The paper presents our initial attempts in building an audio video emotion recognition system. Both, audio and video sub-systems are discussed, and description of the database of spontaneous emotions is given. The task of labelling the recordings from the database according to different emotions is discussed and the measured agreement between multiple annotators is presented. Instead of focusin...

Our goal is to create speaker models in audio domain and face models in video domain from a set of videos in an unsupervised manner. Such models can be used later for speaker identification in audio domain (answering the question ”Who was speaking and when”) and/or for face recognition (”Who was seen and when”) for given videos that contain speaking persons. The proposed system is based on an a...

Computer simulated avatars and humanoid robots have an increasingly prominent place in today’s world. Acceptance of these synthetic characters depends on their ability to properly and recognizably convey basic emotion states to a user population. This study presents an analysis of the interaction between emotional audio (human voice) and video (simple animation) cues. The emotional relevance of...

This paper deals with customers’ behavior in an online environment. The major hypothesis of this paper is that different online product presentation strategies have a different impact on the customer’s choice and that this impact can be measured. The research was conducted using an experimental method based on 6 product groups of 8 products per group. The products were presented with different ...

The World Wide Web has become a primary means of disseminating information, which is being presented increasingly through multiple media. The ability to broadcast audio and video information is becoming a reality with the advent of new media-streaming technologies. Most of the emerging streaming systems require high-bandwidth connections in order to deliver audio and video of suitable quality. ...

Cryptography is the study of mathematical techniques related to aspects of information security such as confidentiality, data integrity, entity authentication, and data origin authentication. Steganography is the science of embedding information into the cover image viz., text, video, and image without causing statistically significant modification to the cover image. Combining these two techni...

In order to satisfy the constantly increasing appetite of consumers for content in today’s world, Personal Video Recorder (PVR) function is implemented in digital TV set-top box (STB) based on Android platform. An algorithm that adjusts video Presentation Time Stamp (PTS) based on audio PTS is presented, which aims at the problem that audio is not synchronized with video existing during playbac...

Obtaining a real-time synchronized video/audio stream through a low bandwidth network is a challenging task. In this paper we address several problems that arise in developing such an application and provide possible solutions to them. These problems include: video related issues such as deciding on the quality of the video and, setting the video parameters to obtain that quality; audio issues ...

In this work, we introduce a dataset of video annotated with high quality natural language phrases describing the visual content in a given segment of time. Our dataset is based on the Descriptive Video Service (DVS) that is now encoded on many digital media products such as DVDs. DVS is an audio narration describing the visual elements and actions in a movie for the visually impaired. It is te...

Audiovisual quality assessment is a relatively unexplored topic. We designed subjective experiments for audio , video, and audiovisual quality using content and encoding parameters representative of video for mobile applications. Our focus were the MPEG-4 AVC (a.k.a. H.264) and AAC coding standards. Our goals in this study are twofold: we want to understand the interactions between audio and vi...
