Aiming at the problem that Two-Dimensional Locality Preserving Projections(2DLPP) only in the horizontal direction of the image data compression and feature's dimension is high,an Alternative Two-Dimensional Locality Preserving Projections(A2DLPP) method is given,and Two-direction data compression Two-Dimensional Locality Preserving Projections((2D)2LPP) is proposed.The algorithm executes 2DLPP separately from both horizontal and vertical directions,so that the image of the horizontal and vertical dimensions is an effective reduction.Experimental results show that both the recognition rate and recognition time of(2D)2LPP are better than 2DLPP and A2DLPP.
