| Abstract(in English) | Fisher Weight Maps method is one of feature extraction methods for image-based pattern recognition. It applies linear discriminant analysis to a set of data matrices composed of local image features, and finds the optimal weight matrix which extracts discriminative features from the data matrices. We investigate two modifications on this method: 1) employing Gabor filtering to extract local features instead of Higher-order Local Auto-Correlation (HLAC), 2) composing the weights for each type of local features (corresponding to scales and orientations of Gabor filters ) instead of the weights for each position. It is shown that the proposed method outperforms the original method on two recognition tasks: facial expression recognition and pedestrian/non-pedestrian recognition. |
