Abstract :
The computational issues for symmetric wavelet transforms are investigated. We present a novel frequency-domain algorithm using the discrete cosine transforms (DCTs) and discrete sine transforms (DSTs). A high efficiency is achieved when this algorithm is applied to signals of finite duration, especially images
