Abdul Nadeem, Yangyu Fan · International Journal of Hybrid Information Technology · 2013
This paper explores the contributions of all reconstruction combinations of the synthesis delay filters in adaptive synthesis filter banks and their effects on objective performance in image compression. It presents a novel comprehensive approach to manage all reconstruction combinations and their placing configuration in the adaptive synthesis filter banks. Based on the contributions of reconstruction combinations, it suggests the most suitable reconstruction combinations in order to reduce the computation complexity of adaptive synthesis filter banks. The simulations are carried out by using popular biorthogonal 9/7 filters on a number of standard test images with different design examples, which show that suggested reconstruction combinations of the synthesis filters play a very vital role on objective performance.
