Abstract

Aiming at reducing the number of iterations in variational method used to reconstruct image gradient field and overlarge data memory space caused by Kronecker’s direct product operation, the paper discusses a matrix transform method to complete the reconstructing of image gradient field. The algorithm maintains the size of matrix constant and requires no iterations and the algorithm’s time complexity and space complexity are O(N), which meets the basic requirements in engineering calculations.
