Soft label based Linear Discriminant Analysis for image recognition and retrieval ?
The proposed label propagation can handle the outliers and multi-density distributed data. The out-of-sample problem of label propagation is solved by using LDA criterion. The proposed method is examined based on extensive simulations for image classification and retrieval problems. Simulation results show the superiority of proposed method to other state-of-art methods.
