Abstract :
Passive Millimeter Wave (PMMW) multi-frame Imaging displacement estimation is a key procedure before Super-Resolution Reconstruction. In this paper, a novel method based on Phase-Only Correlation and IDFT for motion estimation is presented. Experimental data demonstrates that the proposed algorithm yields higher accuracy sub-pixel level motion estimation and proves the effectiveness and adaptiveness of this algorithm.
