摘要：
Displacement measurement for color images using phase-encoded joint transform correlator (PJTC) is proposed. Color reference and target images are decomposed into red, green and blue components. We form new monochromic target and reference images by spatially arranging the three channels. The corresponding displacement of the color images is obtained using the PJTC with the new monochromic target and reference. Our method generates only one sharp peak, and could detect out the displacement of color images accurately. An appropriate hybrid-setup is proposed for pragmatic implementation.
