| Abstract: | The study researches the difference between discrete cosine transform and wavelet transform. The character of DCT above mathematical principle and application is put forward. On the contrary wavelet transform is showed that includes its mathematical principle and peculiarity of frequency division. Finally the relative merits are fouod in picture coding according to their respective performance. |
