A Fast Algorithm for Two Dimension Discrete Cosine Transform
Huang Hua-can · Journal of Huaqiao University · 2007
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.
