Abstract
We evaluate the subpixel accuracy of Discrete Cosine Transform (DCT)-sign phase correlation (-SPC) for image registration. So far, the accuracy was evaluated using images captured by a commercial-off-the-shelf camera, which yields poor results. In the present paper, we use the subpixel-shifted images captured by an industry product camera in order to avoid the problems with a commercial-off-the-shelf camera. We demonstrate the DCT-SPC will be an alternative for phase correlation.
