We present a novel framework for content-aware and art-directable video retargeting. A simple and interactive workflow combines key frame based constraint editing with numerous automatic algorithms for video analysis. This combination gives content producers high level control of the retargeting process. The central component of our framework is a non-uniform, pixelaccurate warp to the target r...

In a recent work, we proposed a method for unequal error protection with Luby Transform codes and showed that it achieves lower bit error rates than a state of the art technique when the information symbols are partitioned into two protection levels (most important and least important). In this paper, we apply our previous work to the problem of video multicast with heterogeneous receivers. We ...

In their article "Perspectives on Video Games as Art" Jeroen Bourgonjon, Geert Vndermeersche, and Kris Rutten engage in discussing whether or not video games can be considered a form of art. Although this question has already been discussed elaborately, the debate is guided by many different and often conflicting positions. The aim of this article is to revisit this debate by mapping out a rang...

In this paper, we give an overview of some advanced computer applications developed in the Computer Vision Laboratory which we used in several art presentations and art installations on the Internet. Already in 1995 we presented on the Internet the Slovenian Virtual Gallery which was a typical first generation web multimedia presentation consisting of an interconnected set of texts, images, and...

We present a novel, end-to-end workflow for content creation and distribution to a multitude of displays that have different dynamic ranges. The emergence of new, consumer level HDR displays with various peak luminances expected in 2015 gives rise to two new research questions: (i) how can the raw source content be graded for a diverse set of displays both efficiently and without restricting ar...

Automatic surgical gesture segmentation and recognition can provide useful feedback for surgical training in robotic surgery. Most prior work in this field relies on the robot's kinematic data. Although recent work [1,2] shows that the robot's video data can be equally effective for surgical gesture recognition, the segmentation of the video into gestures is assumed to be known. In this paper, ...

We answer a question of Aharoni by showing that every separable metric space can be Lipschitz 2-embedded into c0 and this result is sharp; this improves earlier estimates of Aharoni, Assouad and Pelant. We use our methods to examine the best constant for Lipschitz embeddings of the classical `p-spaces into c0 and give other applications. We prove that if a Banach space embeds almost isometrical...

Asymptotic subcone of an unbounded metric space is another metric space, capturing the structure of the original space at infinity. In this paper we define a functional metric space S which is an asymptotic subcone of the hyperbolic plane. This space is a real tree branching at every its point. Moreover, it is a homogeneous metric space such that any real tree with countably many vertices can b...

generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. using visual saliency map for modelling gives important information for understanding in many applications. in this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. the proposed technique i...
