摘要：

In this paper, a displacement measurement for color images using double phase-encoded joint fractional transform correlator (DPEJFrTC) is proposed. Color reference and target images are decomposed into red, green and blue channels. New monochromic target and reference images are formed by spatially arranging the three channels. The displacement of color images is obtained using DPEJFrTC by measuring the new monochromic target and reference. In contrast to the classical joint transform correlator (JTC), our technology generates only one sharp peak and the optical structure is more flexible as well as being able to detect the displacement of color images more accurately. A possible optical set-up is suggested. (C) 2012 Elsevier GmbH. All rights reserved.
