Dual Two-Dimensional Fuzzy Class Preserving Projections for Facial Expression Recognition
This paper proposes a novel algorithm for image feature extraction-the dual two-dimensional fuzzy class preserving projection ((2D)(2)FCPP). The main advantages of (2D)(2)FCPP over two-dimensional locality preserving projections (2DLPP) are: (1) utilizing the fuzzy assignation, mechanisms to construct the weight matrix. which can improve the classification results (2) incorporating. 2DLPP and alternative 2DLPP to get a more efficient dimensionality reduction method-(2D)(2)LPP.
