Facial Expression Creation Using Image Warping and Neural Networks

Abstract

In this paper, we present a method by which different facial expressions can be created from an expressionless face image. In a visual scene our method detects and extracts the position of a face using a neural network based method. The required facial expression can then be created by selecting it from a list of keywords, for example smiling, angry, surprised etc. The user of our method is required to provide only the image and the desired facial expression. The rest of the processes are fully automatic including the selection and detection of the control points necessary to perform the warping. Our warping algorithm is based on the triangulation method that uses triangles to perform warping.
