DEBLURRING USING FRINGE-ADJUSTED JOINT TRANSFORM CORRELATION

An efficient technique for restoring the original from a blurred image using the concept of fringe-adjusted joint transform correlation is p roposed, This technique employs Fourier plane apodization using the re ference image power spectrum to deblur the distorted image, The perfor mance of the proposed technique has been enhanced significantly by emp loying Fourier plane image subtraction, especially for noisy input sce nes involving multiple objects. The image subtraction technique elimin ates the unwanted zero-order term and cross-correlation terms produced by similar input scene objects while alleviating the effect of noise that may be present in the unknown input scene, Computer simulation re sults using noise-free and noise-corrupted input scenes are presented to verify the performance of the proposed technique.
