Abstract

Recently a blind resolution enhancement method that uses a twodimensional and singleinput multipleoutput extension of the constant modulus algorithm has been developed for pure translational motion The method works well in case of low bit depth unobserved true images but its performance decreases for high bit depth true images In this work we propose a refined scheme in which complex representation of images and a set of complex deconvolution FIR filters are used Simulations show that the refined method succeeds in reconstructing the low and high bit depth true images without the knowledge of blur parameters Visual results for the restoration case single image no subsampling are also given No assumption is made about the blurs except that they have lowpass characteristics Also they do not have to be the same for the observed lowresolution images and they do not need to be shift invariant
