The paper presents a real time streaming unit for computing a 3-D discrete wavelet transform.
Abstract
This work presents a fast streaming unit for computing a 3-D discrete wavelet transform. The unit can continuously consume source data and instantly produce resulting coefficients. Considering this approach, every input as well as output sample is visited only once. The streaming unit can be further improved by exploiting suitable SIMD instruction set. Depending on the platform, the proposed method reaches speedup 11× and 8× compared to the naive implementation. The measurements presented in the paper confirm the linear theoretical complexity of the transform. Our method requires a constant amount of time to transform a sample independently of the data size.
