| Abstract: | The expression method of 3-D SDCT(sub-matrices discrete cosine transform) was studied.First,four 3-D matrix operation principles were defined.Then,the transform basic matrix used for 3-D SDCT operation was build and the opera-tion principle of 3-D SDCT was described in detail.Finally,the performance of 3-D SDCT was analyzed.The theoretical analysis shows that the proposed method makes 3-D DCT succinct to express,easy to comprehend and convenient to operate. |
| Keywords: | SDCT transform basic matrix operation performance expression method |
