Abstract

This paper describes a possible strategy to migrate from block-based coding towards object-based coding. We use the results of an intelligent motion estimation algorithm to define low resolution (block based) segmentation. The information from previous segmentation results together with the motion vector field, the image data and spatial relations are used to define the cost to belong to a given object. A separate selection procedure is used to generate the high resolution (pixel based) objects. Afterwards some shape simplification is performed to generate the final objects.
