Abstract: This paper proposed an improved Fast Discriminative Common Vectors (FDCV) classification algorithm based on the traditional Discriminative Common Vectors (DCV).Compared with the traditional DCV,the FDCV not only has a faster classification rate,but also guarantees the same recognition performance.The FDCV does the classification by calculating the distance between scalars but not vectors which are used in the traditional DCV.Theoretical ana-lysis and complexity calculation show that Faster DCV has twice the classifying speed of the traditional DCV.The simulation experiment on the three face databases of Yale Face Database B,ORL Database and PIE Database further verifies the effectiveness of the algorithm.
