Extracting useful features from a scene is an essential step in any computer vision and multimedia data analysis task. Though progress has been made in past decades, it is still quite difficult for computers to comprehensively and accurately recognize an object or pinpoint the more complicated semantics of an image or a video. Thus, feature extraction is expected to remain an active research ar...

due to high speed computer networks, the use of digitally formatted data has increased many folds.the digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. digital watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .di...

Art, music, and science come together as computer musicians and computer scientists collaborate to create EyeMusic, a system for composing and performing eyecontrolled musical and multimedia compositions. In EyeMusic, an eye-tracking device communicates with a musical and multimedia authoring environment to enable composers and artists to sonify and visualize eye movement data. During a live pe...

This piece of research belongs to the field of educational assessment issue based upon the cognitive multimedia theory. Considering that theory; visual and auditory material should be presented simultaneously to reinforce the retention of a mathematical learned topic, a carefully computer-assisted learning (CAL) module is designed for development of a multimedia tutorial for our suggested mathe...

Advances in multimedia acquisition and storage technology have led to tremendous growth in very large and detailed multimedia databases. If these multimedia files are analyzed, useful information to users can be revealed. Multimedia mining deals with the extraction of implicit knowledge, multimedia data relationships, or other patterns not explicitly stored in multimedia files. Multimedia minin...

The Quality of Service (QoS) concept is of central importance in the context of multimedia systems. Generally, multimedia systems comprise the following functional units: networks, end-to-end protocols, data management systems (DMSs), applications, human-computer interfaces, and operating systems. Obviously, the entire system is influencing QoS that is visible to human users at the human comput...

In recent years, the rapid expansion of multimedia applications, partly due to the exponential growth of the Internet, has proliferated over the daily life of computer users (Yang & Hurson, 2006). The integration of wireless communication, pervasive computing, and ubiquitous data processing with multimedia database systems has enabled the connection and fusion of distributed multimedia data sou...

The synchronization problem for audio/visual reproduction has consumed engineers since the advent of recorded audio and images and the first multimedia productions. As computers have evolved to support programmed reproduction of multimedia information, the complexity but not the character or interest have changed. In the digital domain, synchronization problems exist due to data distribution an...

In recent years, there has been a growing interest in multimedia computer systems and applications. We will explore the important challenges that multimedia systems pose to system and application developers, and describe the main issues involved. An overview of the current systems and research in the area and how they have addressed some of these challenges will be provided, with emphasis on th...
