Abstract :
On the basis of two dimensional principal component analysis, an improved two dimensional principal component analysis (I2DPCA) is presented for face recognition. Firstly, the criterion functions of global and between class scatters of projection features are defined. Secondly, the two defined criterion functions are fused by way of multiplication or addition. Therefore, the criterion function of I2DPCA is produced, and the optimal projection axis vector of I2DPCA algorithm is the vector which maximizes its criterion function. Experimental results show that, the correct recognition rate of I2DPCA is higher than that of 2DPCA. In I2DPCA algorithm, the correct recognition rate fused by way of addition is higher than that by way of multiplication.
