Visual Features Extraction Through Spatiotemporal Slice Analysis
نویسندگان
چکیده
In this paper we propose a novel feature extracting method based on spatiotemporal slice analyzing. To date, video features are focused on the character of every single video frame. With our method, the video content is no longer represented with every single frame. The temporal variation of visual information is taken as an important feature of video in our method. We examined this kind of feature with experiments in this paper. The experiment results show that the proposed feature is effective and robust for variant video content and format.

An Enhanced Spatiotemporal Visual Attention Model for Sports Video Analysis
Inspired by the human visual system, visual attention (VA) models seem to provide solutions to problems of semantic image understanding by selecting only a small but representative fraction of visual input to process. Having proposed a spatiotemporal VA model for video processing in the past, we propose considerable enhancements in this paper, including the use of steerable filters for 3D orien...
متن کاملRetrieval Method for Video Content in Different Format Based on Spatiotemporal Features
In this paper a robust video content retrieval method based on spatiotemporal features is proposed. To date, most video retrieval methods are using the character of video key frames. This kind of frame based methods is not robust enough for different video format. With our method, the temporal variation of visual information is presented using spatiotemporal slice. Then the DCT is used to extra...

متن کاملReal-time Action Recognition by Spatiotemporal Semantic and Structural Forests
This paper presents a novel real-time action recogniser by utilising both local appearance and structural information. Our method is able to recognise actions continuously in real-time while achieving comparably high accuracy over state-of-the-arts. Run-time speed is of vital importance in real-world action recognition systems, but existing methods seldom take computational complexity into full...
متن کاملCortical Spatiotemporal Dimensionality Reduction for Visual Grouping
The visual systems of many mammals, including humans, are able to integrate the geometric information of visual stimuli and perform cognitive tasks at the first stages of the cortical processing. This is thought to be the result of a combination of mechanisms, which include feature extraction at the single cell level and geometric processing by means of cell connectivity. We present a geometric...
