- W1986165062 abstract "Object based coding is a new technique that is being investigated to achieve extremely high compression ratios for video sequences. The 'classical' approach to this is a 4 steps algorithm: segmentation, motion estimation and compensation, coding of the segmentation information and finally coding of the prediction errors. In this text we describe another approach where we try to combine these first three steps: try to do the motion estimation and segmentation together and meanwhile collecting important information for the coding the segmentation information. The segmentation is done by finding motion parameters that will yield the best segmentation and growing the segmentation from areas with a good prediction. Coding the segmentation will be done using cost-functions which are calculate in the segmentation step. The actual coding will be done by using simple geometric forms, in our case we used superquadrics, and combining them to arrive at an approximated shape.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.
