This paper presents an approach to infer what is happening in a (crowded) scene using a statistical method. Rather than trying to segment and track the individuals in each frame, our basic idea is to detect salient points (corners) along with their motion vectors. Finally, we obtain statistical measures on this data which are highly correlated with the kind(More)
In this paper, we describe a unique new paradigm for video database management known as ViBE (Video Indexing and Browsing Environment). ViBE is a browseable/searchable paradigm for organizing video data containing a large number of sequences. The system first segments video sequences into shots by using a new feature vector known as the Generalized Trace(More)
This paper presents an unsupervised color segmentation technique to divide skin detected pixels into a set of homogeneous regions which can be used in face detection applications or any other application which may require color segmentation. The algorithm is carried out in a two stage processing, where the chrominance and luminance infor-mations are used(More)
Pseudo-semantic labeling represents a novel approach for automatic content description of video. This information can be used in the context of a video database to improve browsing and searching. In this paper we will describe our work on using face detection techniques for pseudo-semantic labeling. We will present our results using a database of MPEG(More)
The objective of this work is the integration and optimization of an automatic face detection and recognition system for video indexing applications. The system is composed of a face detection stage presented previously which provides good results maintaining a low computational cost. The recognition stage is based on the Principal Components Analysis (PCA)(More)
