Local image features or interest points provide compact andabstract representations of patterns in an image. In this paper, wepropose to extend the notion of spatial interest points into thespatio-temporal domain and show how the resulting features oftenreflect interesting events that can be used for a compactrepresentation of video data as well as for its interpretation. Todetect spatio-temporal events, we build on the idea of the Harrisand Förstner interest point operators and detect localstructures in space-time where the image values have significantlocal variations in both space and time. We then estimate thespatio-temporal extents of the detected events and compute theirscale-invariant spatio-temporal descriptors. Using suchdescriptors, we classify events and construct video representationin terms of labeled space-time points. For the problem of humanmotion analysis, we illustrate how the proposed method allows fordetection of walking people in scenes with occlusions and dynamicback-grounds.
