Abstract: Compressed head-related transfer function (HRTF)(130) parameters are prederi ved or derived in real time for use in filtering an audi o signal for a virtual audio display.  From a frequency domain viewpoint, freq uency components of known transfer functions are smoothe d (125) over bandwidths which are a function of the width of the ear's critica l bands.  In the first implementation, an HRTF is smooth ed (125) by convolving the HRTF (120) with a frequency dependent weighting function i n the frequency domain.  In the second way, the HRTF's frequency axis is warped or mapped into a non-linear frequency domain.</SDOA B>

Granted: 2004-04-13
Abstract: The invention pertains to a method for operating a lighting system with an incoherently-emitting radiation source, in particular a discharge lamp that emits UV, IR or visible-range radiation, by means of dielectrically inhibited discharge, and to a lighting system suitable therefor. The electrodes, which are arranged side by side and separated from each other and the interior of the discharge vessel by dielectric material, are alternatingly connected to the two poles of a voltage source. In operation the voltage source supplies a series of voltage pulses separated by quiescent periods. According to the invention, this produces inside the discharge vessel a spatial discharge which in the regions between electrodes of different polarity is at a distance from the surface of the inside wall of the discharge vessel. Substantial advantages are less stress on the wall of the discharge vessel and greater efficiency in generating radiation.

Title: Motion vector field error estimation
Inventor: BORER TIMOTHY JOHN
IPC: G06T7/20
Filed: 1997-03-03
Granted: 2003-11-11
Abstract: A technique is disclosed for estimating the measurement error in motion vectors used for example in a motion compensated video signal process. For each motion vector corresponding to a region of an image a plurality of temporal and spatial image gradients are calculated corresponding to that region. From the constraint equations of the image gradients a plurality of error values can be calculated for each motion vector and a parameter generated describing the size of the distribution of motion vector measurement errors. Subsequent processing of the video signals using the motion vectors can then be adapted, for example by graceful fallback in motion compensated interpolation, depending on the accuracy of each motion vector. The 'confidence' in the accuracy of each motion vector can be described by a parameter calculated in relation to the size of the error distribution and the motion vector speed.
