Coherent image shape description via the intensity axis of symmetry.
Calculating the IAS for a grey-scale image has been accomplished by computing the SAs for each level curve in the image simultaneously using the active surface model and the image symmetry function. Linking quench mates on the active surface provides an effective method to partition an active surface into the individual axis sheets which comprise the IAS. Because the image regions associated with individual axis sheets often correspond to sensible image structures, the IAS can be used for shape-based image segmentation.
