Interactive Compression of Digital Data
If we can use previous knowledge of the source (or the knowledge of a source that is correlated to the one we want to compress) to exploit the compression process then we can have significant gains in compression. By doing this in the fundamental source coding theorem we can substitute entropy with conditional entropy and we have a new theoretical limit that allows for better compression. To do...
متن کاملSynthetic Aperture Digital Holography
Synthetic aperture is a well-known super-resolution technique which extends the resolution capabilities of an imaging system beyond the theoretical Rayleigh limit dictated by the system's actual aperture. Using this technique, several patterns acquired by an aperture-limited system, from various locations, are tiled together to one large pattern which could be captured only by a virtual system ...
متن کاملAdvances in digital holography
Digital holography development has reached the level, which allows mass-manufacture of large size digital holograms – i-Lumograms, as well as manufacture of colour reflection holograms for security applications. Geola Digital also has proved that colour reflection holograms can be used as auto-stereoscopic projection displays for 3D gaming and home cinema applications. All that became possible ...
متن کاملPhase-shifting digital holography.
A new method for three-dimensional image formation is proposed in which the distribution of complex amplitude at a plane is measured by phase-shifting interferometry and then Fresnel transformed by a digital computer. The method can reconstruct an arbitrary cross section of a three-dimensional object with higher image quality and a wider viewing angle than from conventional digital holography u...

Pawlitzek" 'Department ofPhysics, Dalhousie University, Halifax, Canada "IBM Zurich Research Laboratory, Switzerland out by larger objects, classical diffraction becomes more important. When it eventually dominates the image,we are in the regime of classical wave optics. A hologram is just a complicated interference pattern from which little information about the shape and...
