In this paper the authors analyze the effectiveness of parallel graphics processing unit (GPU) realizations of discrete wavelet transform (DWT) using lattice structure and matrixbased approach. Experimental verification shows that, in general, for smaller input vector sizes along with the larger filter lengths DWT computation based on the direct approach with the use of the direct matrix multiplication significantly f aster t han the application of the lattice structure factorization while fordoi:10.1109/dsmp.2018.8478567 fatcat:425k7xftpzdizlgq3vgxbzcjm4
