A Comparative Evaluation of Current HTML5 Web Video Implementations

HTML5 video is the upcoming standard for playing videos on the World Wide Web. Although its specification has not been fully adopted yet, all major browsers provide the HTML5 video element and web developers already rely on its functionality. But there are differences between implementations and inaccuracies that trouble the web developer community. To help to improve the current situation we draw a comparison between the most important web browsers. We focus on the event mechanism, since it is essential for interacting with the video element. Furthermore, we compare the seeking accuracy, which is relevant for more specialized applications. Our tests reveal varieties of differences between browser interfaces and show that even simple software solutions may still need third-party plugins in today's browsers

Results of a Precrash Application Based on Laser Scanner and Short-Range Radars

International audienceIn this paper, we present a vehicle safety application based on data gathered by a laser scanner and two short-range radars that recognize unavoidable collisions with stationary objects before they take place to trigger restraint systems. Two different software modules that perform the processing of raw data and deliver a description of the vehicle's environment are compared. A comprehensive experimental evaluation based on relevant crash and noncrash scenarios is presented

INFERENTIAL REGION EXTRACTION IN TV-SEQUENCES ABSTRACT

In order to speed up the segmentation of image sequences containing moving objects, an approach is proposed which employs knowledge from different sources to control the extraction of regions. Here, regions are connected image components which exhibit grayvalue characteristics determined by specific values of the parameters supplied to the extraction algorithm. These values may be inferred from outside knowledge and previous interpretation results, e.g. from older frames in a sequence. Various segmentations of the same image with parameters adapted to different expected object surface characteristics may be obtained. Thus, this approach is an attempt to overcome the sharp partition of segmentation and interpretation found in conventional scene analysis paradigms.
