Abstract :
The performance of version I of the discrete cosine transform(DCT-I) is compared to version II of the discrete cosine transform (DCT-II) on various criteria. The results show that for a Markovian signal with correlation coefficient less than 0.8, the DCT-I performs as well as the DCT-II.
