%X LPP has good performance in face recognition,but it is an unsupervised algorithm and has to convert the matrix to a vector which will destroy the image pixel structure,both of which are not beneficial to pattern recognition.To address these problems,proposed an algorithm based on unitary-subspace 2D discriminant locality preserving projection.Based on LPP,the proposed algorithm took the class information into account,performed also 2DLPP in the horizontal and vertical direction to obtain two feature matrixe...
