Filter group delays equalization for 2D discrete wavelet transform applications

作者：

Highlights：

• The cumulative filter delays over the wavelet analysis/synthesis paths are balanced.

• Near-perfect image reconstruction for online/real-time discrete wavelet transform.

• New architecture based on equalizing filter group delays over all calculation paths.
