Field Morphing by using Distance Fields from Bezier Curves

Abstract

The morphing method is very useful in animation field. The morphing method is divided into mesh morphing and field morphing. The proposed method is one kind of the field morphing. The vectors are used for specify the features. In most cases, boundaries of object image are curved, so curves instead of vectors are useful. The features are specified by the distance from the vectors. Our method uses Bezier curves for specifies the features of images. The distance from the curve is defined by Bezier function, and the finding the closest point is easy by using the control points of the distance function.
