Researchers have done a great number of studies on the visual object tracking and the video encoding transmission respectively. However, there are still no public reports about the influence on the visual object tracking raised by the video coding rates. In this paper, for this issue, a typical tracker with the features of HOG and the most commonly-used video encoding methods-H.264/AVC, are chosen...
This contribution addresses generation of natural language descriptions for human actions and behaviour observed in video streams. The work starts with implementation of conventional image processing techniques to extract high-level features from video. Because human is often the most important and also interesting feature, description focuses on humans and their activities. Although feature extraction...
This contribution addresses the approach to creating smooth and coherent description of video streams. Firstly conventional image processing techniques are applied to extract high level features from individual video frames. Natural language description of the frame contents is produced based on high level features. In order to extend the approach to description of video streams, we introduce units...
