Frequency decomposition techniques for increased discriminative 3D facial information capture
Fookes, Clinton B., Cook, Jamie A., Sridharan, Sridha, & Tistarelli, Massimo (2010) Frequency decomposition techniques for increased discriminative 3D facial information capture. In Proceedings of the International Symposium on 3D Data Processing, Visualization and Transmission, Espace Saint Martin, Paris.
Eigen-based techniques and other monolithic approaches to face recognition have long been a cornerstone in the face recognition community due to the high dimensionality of face images. Eigen-face techniques provide minimal reconstruction error and limit high-frequency content while linear discriminant-based techniques (fisher-faces) allow the construction of subspaces which preserve discriminatory information. This paper presents a frequency decomposition approach for improved face recognition performance utilising three well-known techniques: Wavelets; Gabor / Log-Gabor; and the Discrete Cosine Transform. Experimentation illustrates that frequency domain partitioning prior to dimensionality reduction increases the information available for classification and greatly increases face recognition performance for both eigen-face and fisher-face approaches.
