We present a novel 2D metamophosis technique

which uses a distance map to link two shapes.There are three steps.Firstly

the position of a shape is calculated.Secondly

the shape is blended with a distance map.Finally an iterative process isused to linearly interpolate the positions and orientations

and non-linearly interpolate the shapes using morphology.The proposed 2D metamorphosis technique is used for slice interpolation with MRI stack images.The result of shape blending and 3D surface displayingis given.
