Research Abstract

We presented a local descriptor for representing unordered shapes.The descriptor is scale-invariant and suitable when the original whole shapes are similar.In addition, it is suitable even if parts of each original shape are drawn using different scales.Then, we described a landmark placement method for shape analysis by optimization. The method places landmarks well on the contours of the same class objects without an expert about the contours or mathematical assumptions on the contours.
