On Space - Time Interest Points ∗
Local image features or interest points provide compact and abstract representations of patterns in an image. In this paper, we extend the notion of spatial interest points into the spatio-temporal domain and show how the resulting features capture interesting events in video and can be used for a compact representation and for interpretation of video data. To detect spatio-temporal events, we ...

Local image features or interest points provide compact and abstract representations of patterns in an image. In this paper, we propose to extend the notion of spatial interest points into the spatio-temporal domain and show how the resulting features often reflect interesting events that can be used for a compact representation of video data as well as for its interpretation. To detect spatio-...
متن کاملColor Space-Time Interest Points for Live Feed
Interest point detection is the vital aspect of computer vision and image processing. Interest point detection is very important for image retrieval and object categorization systems from which local descriptors are calculated for image matching schemes. Earlier approaches largely ignored color aspect as interest point calculation are largely based on luminance. However the use of color increas...
متن کاملUsing Space-Time Interest Points for Video Sequence Synchronization
We introduce an algorithm for synchronizing two video sequences recorded by stationary cameras. It extends common RANSAC-based approaches that recover either a homography or a fundamental matrix from putatively matched spatial features in two images. In our algorithm, we detect space-time interest points in each sequence which represent events such as objects changing direction, and putatively ...
متن کاملMotion Detection using the Space-Time Interest Points
Space-Time Interest Points (STIP) are among all the interesting features which can be extracted from videos; they are simple, robust and they allow a good characterization of a set of regions of interest corresponding to moving objects in a three-dimensional observed scene. In this study, we show how the resulting features often reflect interesting events that can be used for a compact represen...
