Jun 12, 2013 · The times of Kronecker product operation can be expressed as k = log n N. For the commonly used Lena256.bmp image as an example, the dimensions N of image column vector are N = 256. We pick two basis vectors (n= 2) as the low-dimensional orthogonal vector, so the times we need of the Kronecker product is k = log n N = log 2 256 = 8. Namely, the constructing process only needs eight Kronecker product operations.
