In [21], we proposed the convolution-based parallel 2D-DWT using an extra memory space in order to perform a nearly in-place computation, avoiding the requirement of twice the image size to store the computed coefficients.
During the FFT, in-place computation on an input buffer is performed until the last stage, where stored data are put into the output buffer.
Moreover, it has many advantages compared to the first-generation wavelet such as in-place computation, integer-to-integer transforms, and speed.
Lifting scheme entirely relies on spatial domain and it has many advantages as compared to the convolution method of calculating DWT such as in-place computation, symmetric forward and inverse transforms, and perfect reconstruction.
Results show that the proposed encoder obtains good R/D results for high-resolution video sequences with nearly in-place computation using only the memory needed to store a group of pictures.
It uses O(n3) time in-place computation of maximum matching in a bipartite graph, where the vertices are given in an array, and the existence of an edge between a pair of vertices can be checked by an oracle on demand (from problem specification) in O(1) time.
Results show that the proposed encoder obtains good rate/distortion results for high-resolution video sequences with nearly in-place computation using only the memory needed to store a group of pictures while being able to compress a full HD video sequence in real time.
This scheme has several advantages when compared to the convolution techniques, which includes 'in-place' computation of the DWT, symmetric forward, and inverse transform.
The essence of blockchain lies in its ability to support trustworthy transactions via networked computation in place of human monitor and control.
The theoretical TF-target mRNA expression profiles are calculated for all the genes annotated as TFs and are substituted in place of TFs' profiles during further computation for co-expression calculation.
A number of RFFT computation algorithms and implementations have been proposed for both pipelined and in-place architectures in the literature [1 4].
