Abstract(in English) | In this report, qualitative analyses of ICA and its application for the facial image representation are described. Recently, ICA (Independent Component Analysis) became popular as a new analytical technique for Blind Source Separation problems of EEG and the speech signal, etc. Linear bases found by ICA have interesting characteristics such as non-orthogonality and spatial locality. To urge understanding of these characteristics known by intuition, we conducted experiments with 2D toy-data sets and provided qualitative analyses in comparison with PCA. Next, we applied the ICA for a facial image representation. Unlike previous studies which used raw pixel values with crude shape-normalization, we separated shape and texture of facial images and derived ICA based representations independently for shape and texture. We investigated the effectiveness of this method by recognition experiments of identity and facial expressions. |
