Publication number: 20130039423Abstract: A favorable merging or grouping of simply connected regions into which the array of information samples is sub-divided, is coded with a reduced amount of data. To this end, a predetermined relative locational relationship is defined enabling an identifying, for a predetermined simply connected region, of simply connected regions within the plurality of simply connected regions which have the predetermined relative locational relationship to the predetermined simply connected region. Namely, if the number is zero, a merge indicator for the predetermined simply connected region may be absent within the data stream. In other embodiments, spatial sub-division is performed depending on a first subset of syntax elements, followed by combining spatially neighboring simply connected regions depending on a second subset of syntax elements, to obtain an intermediate sub-division.Type: ApplicationFiled: October 12, 2012Publication date: February 14, 2013Applicant: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventor: Fraunhofer-Gesellschaft zur Foerderung der angew

Publication number: 20130034171Abstract: A better rate distortion ratio is achieved by making interrelationships between coding parameters of different planes available for exploitation for the aim of redundancy reduction despite the additional overhead resulting from the need to signal the inter-plane prediction information to the decoder. In particular, the decision to use inter plane prediction or not may be performed for a plurality of planes individually. Additionally or alternatively, the decision may be done on a block basis considering one secondary plane.Type: ApplicationFiled: October 11, 2012Publication date: February 7, 2013Applicant: Fraunhofer-Gesellschaft zur Foerderung der angewandten e.V.Inventor: Fraunhofer-Gesellschaft zur Foerderung der ange

Publication number: 20130034157Abstract: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.Type: ApplicationFiled: October 11, 2012Publication date: February 7, 2013Applicant: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventor: Fraunhofer-Gesellschaft zur Foerderung der angew

Patent number: 8369537Abstract: For controlling the acoustic reproduction of audio data containing audio elements that are periodically repeated, movement data regarding a movement process is detected. The movement process contains recurring events. Reproduction of the audio data is controlled using the movement data in such a way that at least within a certain period, one out of n audio elements that are periodically repeated is reproduced in synchrony with the moment one of the recurring events occurs (synchronization) or is reproduced temporally offset by a given amount of time from the moment one of the recurring events occurs (offset synchronization). The value n represents a positive integer.Type: GrantFiled: October 12, 2006Date of Patent: February 5, 2013Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V.Inventors: Gerald Bieber, Holger Diener, Malte Korten, Mathias Mainka

Publication number: 20130030819Abstract: An encoder, based on a combination of two audio channels, obtains a first combination signal as a mid-signal and a residual signal derivable using a predicted side signal derived from the mid signal. The first combination signal and the prediction residual signal are encoded and written into a data stream together with the prediction information. A decoder generates decoded first and second channel signals using the prediction residual signal, the first combination signal and the prediction information. A real-to-imaginary transform may be applied for estimating the imaginary part of the spectrum of the first combination signal. For calculating the prediction signal used in the derivation of the prediction residual signal, the real-valued first combination signal is multiplied by a real portion of the complex prediction information and the estimated imaginary part of the first combination signal is multiplied by an imaginary portion of the complex prediction information.Type: ApplicationFiled: October 5, 2012Publication date: January 31, 2013Applicants: DOLBY INTERNATIONAL AB, Fraunhofer-Gesellschaft zur foerderung der angewandten Forschung e.V.Inventors: Fraunhofer-Gesellschaft zur foerderung der angew, DOLBY INTERNATIONAL AB

Patent number: 8363960Abstract: Exemplary embodiments are described in which is performed not only a shot detection (continuous recording with a camera) and an association of several key-frames to the shots, it then being possible for a subsequent scene recognition to be based on the grouping of shots into scenes. Rather, it is observed that a scene only relates to one event in a setting. Since both can change within a shot, not every scene boundary is at the same time also a shot boundary. In addition, not every shot is short enough, so that a reliable retrieval of different picture contents is not guaranteed. Therefore, exemplary embodiments are shown which are capable of defining sub-shots so that in principle, scene and shot boundaries are also sub-shot boundaries at the same time. Sub-shots furthermore include only video pictures with a small change in picture content.Type: GrantFiled: March 20, 2008Date of Patent: January 29, 2013Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V.Inventor: Christian Petersohn

Patent number: 8363768Abstract: In a method for estimating a deviation between a free-running transmitter clock and a reference clock, at a receiver stationary with respect to a transmitter, a transmitter signal generated by the transmitter on the basis of the transmitter clock is received. On the basis of the reference clock, a time of arrival of the transmitter signal and a beat phase of the transmitter signals carrier is determined. On the basis of a clock error model, the time of arrival and the beat phase, the deviation between the transmitter clock and the reference clock is estimated. The clock error model is derived by fitting a correlation function of a stochastic model to a measured auto correlation function of the transmitter clock. Deviations for a plurality of transmitters may be estimated and the transmitters may be virtually synchronized based on the estimations.Type: GrantFiled: March 16, 2010Date of Patent: January 29, 2013Assignees: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V., Friedrich-Alexander-Universitaet-Erlangen-NuernbergInventors: Lucila Patino-Studencka, Andreas Eidloth, Joern Thielecke

Patent number: 8364247Abstract: The invention relates to methods for determining the sex of birds' eggs. It can be used for an early determination of the sex, in particular in poultry farming, and in this respect also with non-incubated eggs. In the method in accordance with the invention, electromagnetic radiation is emitted onto the blastodisk of an egg by a radiation source and, after a switching off of the radiation source, the decay behavior of the autofluorescence intensity excited by the electromagnetic radiation is detected by a detector at the irradiated region of the blastodisk with time resolution and spectral resolution for at least one wavelength of the autofluorescence. The fractal dimension DF is calculated using the determined measured intensity values and the value of the fractal dimension DF is compared with a species-specific and sex-specific limit value, wherein, when the limit value is exceeded, the respective egg is classified as female and, when it is not reached, the egg is classified as male.Type: GrantFiled: December 6, 2010Date of Patent: January 29, 2013Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angwandten Forschung E.V.Inventors: Joerg Opitz, Bjoern Fischer, Petra Morgenstern, Juergen Schreiber, Carola Gerich
