| Abstract: | This paper studies the relation between the discrete cosine transform(DCT) and the discrete hartley transform(DHT).A fast algorithm to calculate the coefficient on two dimension discrete cosine transform(2DDCT) is proposed based on the algorithm of DHT.The new algorithm reduces the complexity of the 2DDCT,and sharply enhances its velocity. |

| Keywords: | discrete cosine transform discrete hartley transform complexity reduce fast |
