Image processing includes techniques that are used to correct defects in images and to enhance the visibility of features of interest. In this note we will look at several different methods for smoothing images in order to remove specks of dust and artifacts from scanning. In future notes we plan to discuss other techniques for enhancing images in the spatial domain including the removal of orientation and lighting defects. Previous discussions [6,7] considered the removal of motion blur in frequency domain using Fast Fourier Transforms.
