| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents a new realization of integer fast lapped transform (LT) with DCT-lifting structure which block-lifting coefficients have DCT matrices. It is obtained by using the block-lifting factorization as our previous work and easy matrix manipulations. Since the proposed FLT has higher coding gain and fewer rounding operations, it shows better coding performance than the conventional methods. The practicality is validated through lossy-to-lossless image compression (coding) simulation which unifies lossy and lossless image coding. | |
