An Extension of Eklundh's Matrix Transposition Algorithm and Its Application in Digital Image Processing
September 1976 (vol. 25 no. 9)
pp. 950-952
R.E. Twogood, Lawrence Livermore Laboratory, University of California
Eklundh's fast matrix transposition algorithm for transposing a 2nX 2nmatrix is extended here to the general case where 2i( j = 1) of its rows will fit into primary storage. The perpormance characteristics of the extension are described and subsuquently compared with those of Eklundh, and its use in a two-dimensional image filtering routine is described.
Index Terms:
Digital image processing, externally stored matrices, fast Fourier transform, matrix transposition, two-dimensional filtering.
