Abstract

The statistical property of Bag of Word (BoW) model and spatial property of Spatial Pyramid Matching (SPM) are usually used to improve distinguishing ability of features by adding redundant information for image classification. But the increasing of the image feature dimension will cause “curse of dimensionality” problem. To address this issue, a dual dimensionality reduction scheme that combines Locality Preserving Projection (LPP) with the Principal Component Analysis (PCA) has been proposed in the paper. Firstly, LPP has been used to reduce the feature dimensions of each SPM and each dimensionality reduced feature vector is cascaded into a global vector. After that, the dimension of the global vector is reduced by PCA. The experimental results on four standard image classification databases show that, compared with the benchmark ScSPM( Sparse coding based Spatial Pyramid Matching), when the dimension of image features is reduced to only 5% of that of the baseline scheme, the classification performance of the dual dimensionality reduction scheme proposed in this paper still can be improved about 5%.
