    A 3-Step Algorithm Using Region-Based Active Contours for Video Objects Detection

    We propose a 3-step algorithm for the automatic detection of moving objects in video sequences using region-based active contours. First, we introduce a very full general framework for region-based active cont...

    An Active Model for Facial Feature Tracking

    We present a system for finding and tracking a face and extract global and local animation parameters from a video sequence. The system uses an initial colour processing step for finding a rough estimate of th...

    Tracking of Objects in Video Scenes with Time Varying Content

    We propose a method for tracking of objects contained in video sequences. Each video object is represented by a set of polygonal regions. A bottom up approach (spatial segmentation/motion estimation) is applie...

    Combined Frequency and Spatial Domain Algorithm for the Removal of Blocking Artifacts

    A novel combined frequency and spatial domain method is presented in this paper for blockiness reduction for low bit rate compressed images. The method consists of two stages: in the first, better estimates of...

    Temporal Segmentation of MPEG Video Streams

    Many algorithms for temporal video partitioning rely on the analysis of uncompressed video features. Since the information relevant to the partitioning process can be extracted directly from the MPEG compresse...
