Abstract:
Active Appearance Models (AAM) provide a compact statistical model of data encom- passing both shape and texture variations. This report introduces a novel and fast search algorithm for AAMs based on canonical correlation analysis (CCA). In contrast to the standard AAM matching approach CCA exploits the correlation between texture residuals and model parameters more efficiently. In a set of experiments using face and medical images we show that CCA based search consistently outperforms the convergence speed of the standard method by a factor of four. The time needed for training is reduced by 80%. Since the implementation effort of the standard approach and CCA are similar our results suggest that CCA can replace the standard AAM search.
