ABSTRACT:
A method derives edge extensions for wavelet transforms and inverse wavelet transforms of two-dimensional images. The method overcomes the necessity of side computations by treating the two-dimensional matrix of values as a one-dimensional array of values. The use of a one-dimensional array reduces the required flushing and loading of registers by allowing the flushing and loading to be performed in between frames, rather than in between rows or columns of the matrix.
