                         segmentation based video coding aimed at low-bit rate application. 
                         The most significant contribution is the algorithm for the 
                         segmentation of videoconference image sequences for content-based 
                         coding. The segmentation is based on motion estimation trough the 
                         computation of the optical flow field and motion segmentation by 
                         applying a Graph-Theoretical clustering. The algorithm will be 
                         added to the video codecs of the OpenH323 project which is based 
                         on H.323 ITU-T Recommendation. This visual collaboration 
                         environment for Desktop, composed of terminals, gatekeepers and 
                         MCU (Multipoint Control Unit), has already been implemented and 
                         tested. It is particularly convenient for academics 
                         implementation, the software is freely distributed, and its code 
                         can be modified according to the needs of the user. However, the 
                         first tests using the H.261 codec showed a video delay of 3 
                         seconds, confirming the need to optimize the video codec.",
