Fast Registration of Tabular Document Images Using the Fourier-Mellin Transform
… of a novel, locally adaptive foreground-background segmentation algorithm, based on the median filter. The background removal algorithm is also demonstrated as a useful tool to remove ambient signal noise during correlation. Common problems with FMIR are eliminated by background removal, …

Vision based methodology for evaluation of meat quality characteristics : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… The first step in image pre-processing was background removal. Edge enhancement, filtering and/or sharpening techniques were then used to remove any noise present and to enhance the visual quality of the images. Proper segmentation algorithms are very important for a successful vision …
