The paper presents interactive learning tools used in courses in automatic control at Lund Institute of Technology. The learning tools are aimed at improving the understanding of and intuition for the abstract parts of the control courses. The paper presents dynamic interactive modules for a course in sampled-data systems. The tools are implemented in Matlab and used over Internet.

The increasing popularity of virtual, augmented, and mixed reality (VR/AR/MR) applications is driving the media industry to explore creation delivery new immersive experiences. One trends volumetric video, which allows users content unconstrained by traditional two-dimensional window director’s view. ISO/IEC joint technical committee 1 subcommittee 29, better known as Moving Pictures Experts Gr...

Video is taken advantage of in different educational settings. In the simplest cases, teachers might present movies on video to their students in the classroom. In more advanced cases, videos might be made during exercise and training in order to provide visual and dynamic feedback to the trainees, for example. In educational settings, very often videos are watched, commented on and analyzed in...

Motion video data consists essentially of a time-ordered sequence of pictures, and cameras typically generate approximately 24, 25, or 30 pictures (or frames) per second. This results in a large amount of data, and therefore demands the use of compression. For example assume that each picture has a relatively low \QCIF" resolution, i.e., 176 144 samples, that each sample is digitally represente...

Recent years have witnessed an explosion of multimedia contents available. In 2010 the video sharing website YouTube announced that 35 hours of videos were uploaded on its site every minute, whereas in 2008 users were “only” uploading 12 hours of video per minute. Due to the growth of data volumes, human analysis of each video is no longer a solution; there is a need to develop automated video ...

The dynamic growth of multimedia production and multimedia enabling devices increase a need for a way that can store, manage, access and share the multimedia data. The explosion of digital media content is driving the need for more effective solutions for annotation, managing and effective searching large repositories of video to fulfill the demand of viewers. Of all media types only the video ...

We address the problem of automatically analyzing hockey scenes by estimating the panning, tilting and zooming parameters of the broadcasting cameras, tracking hockey players in these scenes, and constructing a visual description of the scenes as trajectories of those players. Given quite fast and non-smooth camera motions to capture highly complex and dynamic scenes of hockey, tracking hockey ...

Video streaming over a hostile environment such as the Internet, where the available bandwidth varies in time, requires the source to adjust its transmission rate dynamically. Moreover, inevitable packet losses cannot be totally avoided and, hence, the video-streaming schemes should be complemented with appropriate error concealment techniques. In this paper, we highlight the vitality of the bi...

Abstract: Relevant past events can be remembered when visualizing related pictures. The main difficulty is how to find these photos in a large personal collection. Query definition and image annotation are key issues to overcome this problem. The former is relevant due to the diversity of the clues provided by our memory when recovering a past moment and the later because images need to be anno...

This chapter presents a novel approach for automatic annotation and content based video retrieval by making use of the features extracted during the process of detecting commercial boundaries in a recorded Television (TV) program. In this approach, commercial boundaries are primarily detected using audio and the detected boundaries are validated and enhanced using splash screen of a program in ...
