- Abstract:

This paper proposes face recognition software that uses twodimensional principal component analysis (2DPCA) in conjunction with partial feature weighting by applying twodimensional partialweighting to the characteristic subspace. First faces are mapped onto this partially weighted 2DPCA subspace, then the samples are classified by calculating the distance from the samples to the partially weighted 2DPCA subspace. To test this new method, ORL face databases were used and it was found that the recognition rate was higher than with either 2DPCA or PCA and the computational complexity did not increase significantly.
