Abstract: | A new APM computer-generated hologram algorithm for minimizing DC components and more effective data recovery is presented for the purpose of an ID tag application. In this method, a technique of randomization of the input data is introduced prior to the Fourier transform. As a result, DC components are localized at the center region, which is only 1 data cell, regardless of input data. The size of the tag pattern is reduced 2.25 times using a color encryption technique. Our experimental result through the image captured by a camera also shows that approximately 50% damaged APM-CGH tags can be reconstructed at a low error rate of about 1.8%. |
