| Research Abstract |
We proposed a novel tensor based learning method called generalized N-dimensional principal component analysis(GND-PCA) for multi-dimensional data analysis. We also proposed a framework based on GND-PCA and a 3D shape normalization technique for statistical volume(texture) modeling of the liver. The 3D shape normalization technique is used for normalizing liver shapes in order to remove the liver shape variability and capture pure texture variations. The GND-PCA is used to overcome overfitting problems when the training samples are too much fewer than the dimension of the data. The preliminary results of leave-one-out experiments show that the statistical texture model of the liver built by our method can represent an untrained liver volume well, even though the mode is trained by fewer samples. We also demonstrate its potential application to classification of normal and abnormal(with tumors) livers.
