Query: Optimization of the n-dimensional sliding window inter-channel
  correlation algorithm for multi-core architecture   Calculating the correlation in a sliding window is a common method of
statistical evaluation of the interconnect between two sets of data. And
although the calculation of a single correlation coefficient is not
resource-intensive and algorithmically complex, sequential computation in a
large number of windows on large data sets can take quite a long time. In this
case, each value in the data, falling into different windows, will be processed
many times, increasing the complexity of the algorithm and the processing time.
We took this fact into account and optimized the correlation calculation in the
sliding window, reducing the number of operations in the overlapping area of
the windows. In addition, we developed a parallel version of the optimized
algorithm for the GPU architecture. Experimental studies have shown that for a
7x7 correlation window sliding in one pixel increments, we were able to
accelerate the processing of an 12 MPixel image pixels on the GPU by about 60
times compared to the serial version running on the CPU. The article presents
an optimized version of the algorithm, a scheme for its parallelization, as
well as the results of experimental studies.
