摘要： The present invention relates to a method for sharpness enhancing digital image data (I, ID). A basic idea is to choose the degree of enhancing the sharpness in a local manner to thereby enhance only local parts of the underlying image (I) and to thereby avoid or reduce enhancing noise components contained in the underlying image (I).

摘要： The present invention relates to a method for classifying digital image data (ID) which solves the problem that images (I) having image areas with artificial text overlay have to be detected and classified in video signals in a reliable manner. Therefore, a robust detection in the presence of additive noise is proposed which can be invariant with respect to interlaced or progressive modes of video sequences.

摘要： An imaging unit including a first spectral splitting and illumination part and a second spectral splitting and recombination part. Within the first spectral splitting part received white light is split up into a first spectral component and a second spectral component. In the second spectral splitting part the second spectral component is split up into a third spectral component and a fourth spectral component. Additionally, first, second, and third partial images of an image to be generated are produced with respect to the first, third, and fourth spectral components of the white light. The first, second, and third partial images are recombined to obtain a recombined or reproduced image. The second spectral and polarization selective splitting and recombination part includes a dichloric beam splitting device and first and second polarization selective or polarizing beam splitting devices.

摘要： A method to denoise a stereo signal which comprises a stereo sum signal (Us(z)) and a stereo difference signal (Ud(z)), wherein a stereo to mono blending on basis of an attenuation of the stereo difference signal (Ud(z)) is performed, determines an attenuation of the stereo difference signal (Ud(z)) under consideration of the difference signal amplitude.

摘要： The present invention generally relates to the field of wireless communication systems. It particularly refers to a spatial diversity transmitter (110) and a spatial diversity receiver (120) in a wireless multiple-input multiple-output (MIMO) spatial multiplexing system as well as a corresponding method for wirelessly transmitting and receiving modulated RF signals via multiple wireless signal propagation paths (Pl) of a multipath fading channel in a way that correlation between the MEMO channel components are reduced and/or the signal to interference plus noise ratio (SINR) is increased which hence result in an improved bit error rate (BER) or packet error rate (PER) performance of said wireless MIMO spatial multiplexing system. On the receiver side, for example, this is achieved by controlling at least one antenna switching and/or combining means (121a′+b′) to select a specific combination of different fixed beam antennas (121a+b) from each receiver-resident antenna array. According to the invention, said selection is based on estimated values of the channel impulse responses (hl(τl, t)) for said signal propagation paths (Pl). An antenna beam selection control means (129) is configured for selecting a specific antenna beam combination so as to maximize the average signal-to-interference-plus-noise ratios ( γl) of RF signals (rl(τl, t, φl)) received via said multiple wireless signal propagation paths (Pl) and/or to minimize the correlation coefficients (ρrl1rl2(t)) indicating the correlations of different pairs of these RF signals (rl1(τl1, t, φl1) and rl2(τl2, t, φl2)).Thereby, each fixed beam antenna (121a+b) of the receiver-resident antenna arrays has a distinct radiation pattern with a different beam center and/or beam width in the azimuth and/or elevation plane, wherein a superposition of all these radiation patterns may cover all possible azimuthal (φ) and/or elevational angles of arrival (θ) of an RF signal (s(t)).For compensating detected multipath fades in the channel amplitude response (|Hl(f, t)|) of at least one signal propagation path (Pl) between the spatial diversity transmitter (110) and the spatial diversity receiver (120), a receiver-resident channel estimation and/or equalization circuitry (124, 128) is applied.

摘要： A radio transmission signal consisting of signal frames that comprise a dynamic data part and a quasi-static data part according to the present invention is characterized in that the dynamic data part of a respective frame contains an indicator showing in which following frame the quasi-static data part of this respective frame will be repeated. Therewith, an alternative frequency of e.g. a digital shortwave signal like a DRM signal can easily and satisfactorily be checked before a fast seamless switching to this alternative frequency can be performed. The inventive method to perform a seamless switching of a receiver from a first currently tuned frequency to a second alternative frequency is characterized by the step of receiving at least one set of samples from a respective signal transmitted on at least one second frequency during a time period during which said indicator assures that it is secure that only data that has been transmitted at least once is transmitted as signal on said first frequency to gather some information about said alternative frequency.

摘要： A method to perform a cycle synchronization between interconnected sub-networks, in which a reference node connected to one of the sub-networks transmits a respective cycle time information to cycle masters of all other sub-networks at recurring time instants, and the cycle masters of all other sub-networks adjust their cycle time accordingly. An adjustment of the cycle time within a cycle master is performed by determining a first time interval (t1, t1′) in-between two receptions of cycle time information from the reference node with an own clock, determining a second time interval (t2, t2′) in-between two corresponding transmissions of cycle time information from the reference node on basis of the received cycle time information, comparing the first time interval (t1, t1′) and the second time interval (t2, t2′), and adjusting the own cycle length according to the comparison result.
