Coherent lensless matched filter and an application to feature extraction in character recognition
Reduction of space variance in coherent matched filtering is considered in the context of parallel character recognition. The space variance due to vignetting apertures is eliminated by synthesizing the effect of the second lens of the Vander Lugt matched filter (MT) inside the hologram. This leads...
