A joint transform correlator with minimum variance in peak intensity using Lagrange multipliers has been designed in cases of both input zero‐mean noise and nonzero‐mean noise. Space‐domain‐based reference functions were proposed to achieve distortion‐invariant image recognition. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 190–192, 2001.
