Abstract
The article discusses methods for compressing information about the boundaries of areas generated by superpixel image segmentation. The representation of superpixel boundaries in the form of a four-digit image generated by boundary elements is proposed. A new compression method for this image is developed, based on constructing the trajectories of the boundary elements and then encoding them. An experimental study of the new method demonstrates its advantages over known methods of statistical coding and predictive coding, especially for large superpixel sizes.
