Abstract: A selected channel of a multi-channel signal which is represented by frames composed from sampling values having a high time resolution can be encoded with higher quality when a wave form parameter representation representing a wave form of an intermediate resolution representation of the selected channel is derived, the wave form parameter representation including a sequence of intermediate wave form parameters having a time resolution lower than the high time resolution of the sampling values and higher than a time resolution defined by a frame repetition rate. The wave form parameter representation with the intermediate resolution can be used to shape a reconstructed channel to retrieve a channel having a signal envelope close to that one of the selected original channel. The time scale on which the shaping is performed is shorter than the time scale of a framewise processing, thus enhancing the quality of the reconstructed channel.

Abstract: The invention provides a panel comprising a first light emitting area (1) for providing light of a first color and a second light emitting area (2) for providing light of a second color different from the first color, the first and second light emitting areas being separated from each other by a first spacing (3) along a first spacing axis (5) perpendicular to a normal of the panel, wherein the first spacing (3) is smaller than 5 micrometer. Preferably The Width (4) of the at least one of the light emitting areas is also smaller than 5 micrometer. As these spacings and/or dimensions approach the wavelength of light emitted by the light emitting areas, the boundaries between these areas become blurred or even the areas become indistinguishable from each other due to mixing. A Panel of the invention can be advantageously used in lighting and or display devices, in particular those that magnify the light emitting areas towards their users, such as autostereoscopic displays having lenticular lens arrangements.

Abstract: A system and method is described by which so-called standard angiographic views can be generated using a 3-or 4-D reconstructed image of the object of interest. One preferred example is the reconstruction of coronary angiograms from rotational angiography sequences. Once the 3D image is created, it can be forward projected into the user-defined “standard” views for live presentation during the procedure. It is anticipated that these standard views, which more closely mimic what a physician is accustomed to see, will be more readily accepted by the interventional community.
