Abstract
A new method for image figure segmentation using morphological techniques is proposed. Morphological skeleton transform, which extract a medial axis of an input figure, is known to have an advantage that the original figure can be reconstructed from its resulted skeleton. At the same time, the skeleton is dissociated at constricted parts (or necks) of the input figure.
In this method, we utilize these two properties for segmentations. First, we take the morphological skeleton for the input image figure. Then, we reconstruct the original figure part by part separatedly from each of dissociated skeletons, and obtain segmented figures.
It will be a great advantage that, in this method, such a global image analysis as figure segmentation can be achieved only using steps of local morphological operations.
