Abstract:
The algorithm used for the segmentation of animage, and scheme used for the representation of the segmentation result are mostly selected based on the final image analysis or interpretation objective. The boundary based image segmentation and representation system developed by Nabors segments and stores the result as a graph-tree hierarchical structure without any kind of prior knowledge of the final image analysis or interpretation objective [1]. The representation allows the development of efficient feature extraction and interpretation algorithms to support diverse image processing applications such as object recognition, scene matching, content based image retrieval, etc. This paper shows that Nabors’ hierarchical representation of curves is not invariant to rotation, and proposes an enhanced representation which retains its structure and remains invariant under rotation. The new representation makes it easy to determine if a curve is a section of a larger curve.
