Diagonal vectorisation of 2-D wavelet lifting
David Barina, Pavel Zemčík · 2014
With the start of the widespread use of discrete wavelet transform in image processing, the need for its efficient implementation is becoming increasingly more important. This work presents a novel SIMD vectorisation of 2-D discrete wavelet transform through a lifting scheme. For all of the tested platforms, this vectorisation is significantly faster than other known methods, as shown in the results of the experiments.
