Abstract : In this thesis digital image Super-Resolution techniques using the ExpectationMaximization (EM) and Maximum a posteriori (MAP) techniques are discussed. ASuper-resolution algorithm using the EM algorithm in the frequency domain takingadvantage of the diagonalization property of the DFT is discussed. Super-resolutionusing a combination of EM and MAP algorithms is also presented.We have considered the problem of obtaining a high resolution (HR) image frommultiple low resolution (LR) frames. For this approach, the low resolution framesare required to have sub-pixel shifts among them, thus making each low resolutionframe provide unique information about the scene which can be used to constructa high resolution frame. A method for interlacing the multiple LR frames to forma high resolution grid is discussed. This approach reduces the complexity of thesuper-resolution algorithm and provides for e.cient implementation in the frequencydomain.Point spread function (PSF) estimation, which is critical to the quality of the .nalimage is also discussed. The practical scenario in which the PSF is,.............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
