Object contours resulting from segmenting images or video frames can be efficiently encoded using B-spline functions. An unsolved problem is how to divide a given contour into segments such that the resulting compression is optimal in rate-distortion sense. In this paper we describe two techniques for finding a close-to-optimal knot assignment. The first technique prunes an accurate B-splines approximation...
This paper presents the concept of content recommendations for the production of multi-channel TV shows. Within the 6 Framework project "LIVE- Live Staging of Media Events " [3] we are developing a production support system which will have a functionality of content recommendations and will support production of multi-channels programs. The paper outlines a concept of a multi-channel show...
The proliferation of interactive digital TV applications will depend on their complexity and ease of use. The investigation of simple, intuitive human-machine interfaces is therefore crucial for their success. While the operation of most home devices is today based on using remote control, in this paper we investigate an alternative solution using a visual input of the users's gestures. The proposed...
The proliferation of interactive digital TV services will depend on their complexity and ease of use. The investigation of simple, intuitive human-machine interfaces is therefore crucial for their success. Personalized iTV services require consumer authentication and consumer input, which is traditionally done by using the remote control. In this paper, we investigate alternative ways to collect consumer...
Today's TV broadcasting companies are highly professionalized in the production of linear TV formats. Workflows and technologies for these linear formats are reliable, the production personnel are highly skilled and we can trust in well-known viewing habits of the consumers. The key issue of this paper is: how do we enable such a broadcasting working environment to produce by far more variable, multi-perspective...
