摘要
Disclosed herein is a method, system and computer readable medium for a distortion-tolerant 3-D object recognition that may include recording a single exposure digital hologram of a 3D object on a sensor by on-axis digital holography; representing the recorded single exposure digital hologram mathematically as a synthesized hologram and as a reconstructed complex wave function of the 3D object; repeating the steps above for at least one comparison 3D object and obtaining a comparison reconstructed complex wave function of the comparison 3D object; and constructing a correlation filter for 3D distortion-tolerant object recognition from the reconstructed complex wave function of the 3D object and from the at least one comparison reconstructed complex wave function of the comparison 3D object also recorded; and correlating the reconstructed complex wave function of the 3D object to the comparison reconstructed complex wave function of the comparison 3D object using the correlation filter in order to recognize 3D objects.
