Abstract
A four-band decomposition module for 2D digital signals is proposed. The total amount of the error due to the rounding operation is reduced under the constraint that the module has compatibility with the conventional wavelet transform in JPEG 2000. The number of rounding operations and the standard deviation of the error are reduced by 33.3 and 22.9%, respectively, per one module
