Deformation method for 3D identikit creation

An identikit is a model of a head created for a purpose of identification. Nowadays, the police use mostly 2D portrait identification, which is simple but has limited possibilities. Therefore, 3D head models have started to be used as identikits. In this paper, we propose small improvements of Free-Form Shape Deformation (FFSD) for 3D identikits creation, which allow modeling new shapes and keeping important details. With these improvements the FFSD method is able to create various and realistic deformations of a human head model which are necessary to make and identikit is a bit quicker. The improved method has been implemented and used in software prepared for the police.
