OPTIMAL BIT ALLOCATION IN THE PARAUNITARY SUBBAND IMAGE CODER BASED ON THE QUATERNION ALGEBRA
Abstract
The problem of bit allocation in the context of the tree structure 2D paraunitary filter bank based on the quaternion algebra, i.e. 4-band packet wavelet transform, is considered. It was shown that the bit allocation is optimal if the quantizers error variances in the encoder channels are equaled.
