The occam-π language provides many novel features for concurrent software development. This paper describes a video processing framework that explores the use of these features for multimedia applications. Processes are used to encapsulate operations on video and audio streams; mobile data types are used to transfer data between them efficiently, and mobile channels allow the process network to...

Web cameras are becoming more and more common on the Internet, and the technology is ready to make cameras a standard accessory of any computer. The development of applications, however, hasn’t followed the explosive diffusion of the cameras. Problems in developing applications for remote web cameras come from the low image quality that they generally provide and from the fact that, unless the ...

Driven by the rapidly increasing demand for audio-visual applications, digital video compression technology has become a mature field, offering several available products based on both hardware and software implementations. Taking advantage of spatial, temporal, and statistical redundancies in video data, a video compression system aims to maximize the compression ratio while maintaining a high...

We present an algorithm that approximates the output of an arbitrary video processing algorithm based on a pair of input and output exemplars. Our algorithm relies on learning the mapping between the input and output exemplars to model the processing that has taken place. We approximate the processing by observing that pixel neighborhoods similar in appearance and motion to those in the exempla...

This paper summarizes an ongoing work in multimedia processing aimed at the automated archiving and selective retrieval of textual, pictorial and auditory information contained in video programs. Video processing performs the task of representing the visual information using a small subset of the video frames. Linguistic processing refines the closed caption text, generates table of contents, a...

Title of dissertation: VIDEO PROCESSING WITH ADDITIONAL INFORMATION Mahesh Ramachandran, Doctor of Philosophy, 2010 Dissertation directed by: Professor Rama Chellappa Department of Electrical and Computer Engineering Cameras are frequently deployed along with many additional sensors in aerial and ground-based platforms. Many video datasets have metadata containing measurements from inertial sen...

This paper discusses the programmable and dedicated approaches for real-time video processing applications. Various VLSI architecture including the design examples of both approaches are reviewed. Finally, discussions of several practical designs in video processing applications are then considered in VLSI architectures to provide significant guidelines to VLSI designers for any further real-ti...

In the past few decades, the importance of video signal processing in the communication industry has expanded drastically. Simple broadcasting can no longer satisfy the demands of the public. As a result, multi-media has became one of the fastest growing business in the industry. Because of the large data processing involved, software implementation of video algorithms for real-time purpose is ...

Video processing applications are now in demand on a great variety of platforms such as mobile devices or high performance servers. On the other hand, a great variety of performance is required for video processing applications such as high throughput, good accuracy, long battery life, and so on. Therefore, programmers today should study hard about various platforms and techniques under the pre...
