Citation Context ...Image morphing is an important area due to its applications in the creation of special visual effects for entertainment in film, television industry [39,32], in education and in the field of medicine =-=[9]-=-. These effects are generated by smooth transformation of the objects and the colors of one image to the objects and the colors of another image. For this purpose, several spatial domain image morphin... |

In layer based morphing technique =-=[12]-=-, objects are segmented into regions in the form of separate layers. Morphing is done between specific object segments. In this technique, ghost effect is locally minimized. Image morphing using piece... |

A 3D real time registration technique is given by SY Park et. el. in =-=[28]-=-. The technique is point-to-point based and exploits the power of graphical processing unit (GPU) for image registration. The technique uses points pair to define the line segments and a mapping funct... |
