Outline Problem Statement Prior Art: Portraiture Morphing Approaches Results Conclusion Future Works

Problem Statement Image morphing == Image metamorhposis Creating a smooth transformation of one

digital image to another Application:

Movie Criminal Matching Plastic Surgeon

Problem Statement Basic techniques used:

Cross dissolve A source image is faded out while letting a

destination image faded in simultaneously, to create a smoothing of one to another

Image warping It is a technique that involves geometrical

transformation and interpolation of objects.

Problem Statement Cross Dissolve Result:

Problem Statement Image warping Result:

Problem Statement Image warping Result:

Problem Statement Visual Effect depends on

Transition Control How importance is each pixel in the morphing

process?

Smoothness Will the changes give smooth result?

Problem Statement Transition Control and Smoothness

Problem Statement Existence Approaches:

Mesh Warping Field Morphing Radial Basis Function Energy minimization Multilevel Free-Form Deformation Work minimization

Portraiture Morphing Field Morphing

Use of control linesFor each pixel X in the destination image

find the corresponding u,v find the X' in the source image for that u,v:

destinationImage(X) = sourceImage(X')

What have been done? Survey on Image morphing method

Field Morphing Artistic face ratio Implementation

What can be done? Face prediction

Application: Use of one generation’s images to predict the preceding generation and succeeding generation

3D Face morphing Apply the sculpture dimension on art to

construct or morph the 3D face.
