Abstract
We investigate the design of lapped orthogonal transforms for data compression of images. We present some properties and new results of paraunitary filter banks. We concentrate on the case where the filter length L=2K, where K is the number of channels. The aim is to design perceptually relevant filters, i.e., linear-phase filters that smoothly decay to zero at the boundaries
