Abstract  Neighbourhood preserving embedding (NPE) is a subspace learning algorithm, which aims at preserving the local neighbourhood structure on the data manifold, and it is a linear approximation to Locally Linear Embedding (LLE). When image data are concerned, the dimensionality of vectorized image data is usually high. NPE can not be implemented due to singularity of matrix. NPE is extended to 2 dimensional senses, 2DNPE, which directly extracts image feature from 2D image matrices rather than from 1D vectors as NPE does. The proposed algorithm is evaluated on Yale face database and Binary Alpha digits database.
