Action Change Detection in Video Based on HOG

Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...

Statistical sequential analysis for real-time video scene change detection on compressed multimedia bitstream

The increased availability and usage of multimedia information have created a critical need for efficient multimedia processing algorithms. These algorithms must offer capabilities related to browsing, indexing, and retrieval of relevant data. A crucial step in multimedia processing is that of reliable video segmentation into visually coherent video shots through scene change detection. Video s...

A Real-time Video Object Segmentation Algorithm Based on Change Detection and Background Updating

This paper proposes an efficient automatic video object segmentation algorithm by combining change detection with background updating. First, motion information is obtained from difference between previous frame and current frame instead of complicated motion estimation. Second, background subtraction is introduced to solve the problems of still object and uncovered background an ill-posed in c...

Speaker Change Detection based on Mean Shift

To settle out the problem that search of speaker change point (SCP) is blind and exhaustive, mean shift is proposed to seek SCP by estimating the kernel density of speech stream in this paper. It contains three steps: seeking peak points using mean shift firstly, using maximum likelihood ratio (MLR) to compute the MLR value of the peak points secondly, and seeking SCPs from MLR value using the ...
