The positive/negative sign code of the DCT coefficients is important to reconstruct the structural information of image. However, since the quantity of each sign code is 1[bit/pel], the efficient reduction method for sign code is required. In this paper, more important area on the 2-D spatial domain for the sign code is determined to increase the image quality of the reconstructed image, and we have discussed the efficient preservation method of the sign code using the parameters in the obtained important area. |
