Animation morphing using piecewise wrapping on local environment / Mickle Anak Lutu

This project present an appropriate way to morph a facial expression by applying a piecewise warping technique, which is using bilinear function. In which we apply a simple transformation locally but allow that transformation to vary across the image. An advantage of this approach is that we can leave some areas of the image unchanged whilst warping other to the significant degree. While local warping appear to be a promises method to warping image. Its effectiveness still has to be future proved. The process of using piece wise warping operation that require user first to define a center point. The purpose of center point is to determine the specific area of image to be warp. The four grids will appear on the top of the image. Next, user has to define four control points corresponding to the grid on source image and four control points on the image to be warped later. There are eight coefficients to be determined, but the four corner points are sufficient to solve for them exactly. Furthermore, the facial images must in the 2D. In this respect, an image is a non planar with a grey scale.
