The invention relates to a method and an apparatus for creating facial images, more particularly to a composite picture system and method utilising a library of basic facial components. In typical composite picture systems, the process of creating facial images includes the steps of selecting various facial components, herein designated as basic morphological elements, from a library and assembling them. The novel method comprises the introduction of a component calibration step allowing the different basic morphological elements of a facial image to be merged into a single synthetic facial image with proportional components. A universal skin tone, created using a set of filters on the original images, is also used to reduce the contrasts between the individual basic morphological elements. In addition, each basic morphological element is encoded and uniquely describes each facial image. The use of the encoding facilitates the transmission of such images requiring only the code to be sent. The invention further provides a computer readable medium comprising a library of basic morphological elements and a program element that direct a computer to implement the composite picture process. |
