Rigid Bones Grouping Scheme for Facial Expressions Synthesis Utilizing Three-Dimensional Head Model
In the recent years the demand for intuitive communication between user and machine is growing. Therefore, the synthesis and analysis of emotions play significant role in computer systems [1]. Facial expressions can improve man-machine interactions, because the human face is natural medium of communication. We have created threedimensional model according to face topology and anatomy.

متن کاملThe Krapina Occipital Bones
The Krapina fossils are the largest collection of Neandertals known, representing a unique opportunity to examine Neandertal variation at a single place and time. Because of the nature of the assemblage, knowledge about the collection as a whole must be obtained from the analyses of the individual skeletal elements. In this work I present a summary of a subset of the Krapina fragments, the occi...
