7. A fundamental problem in microscopy originates from imaging speci-
mens thicker than the DOF of microscope objective lens. Digital image
fusion provides an effective software-based solution by generating
extended DOF images that maximize the amount of accessible structural
information available in microscope images.
8. The central idea of applying digital image fusion to generate an
extended DOF microscope image is to assemble from different optical
section images the components that contain the most in-focus informa-
tion into a composite image. These optical section images should be
captured along the z-axis, with a translation step Dz that is no larger
than the DOF of the imaging system, and the whole set of images covers
approximately the desired ...
