The invention relates to a method and an arrangement for connecting packet-oriented communication terminals, wherein a first communication terminal (P1) is arranged in a first network (LAN), the first network (LAN) being connected to a second network (INT) via a network address-translating unit (NAT), a second communication terminal (P2) being arranged in said second network. For this purpose, a proxy (P) is provided in the gateway (GW) for intercepting or listening to messages, in that a STUN, ICE, or TURN protocol is implemented. The concept of the invention is to implement, on a case by case basis, IP address spoofing or port number spoofing and a “RESPONSE ADDRESS” STUN field in the proxy, thereby performing the STUN or ICE protocol not on the respective communication terminals, but at a third part on another unit. A performance takes place even if the central unit is not located in the user data path between the STUN server STUN and the respective communication terminal.

A summing circuit for an adder decodes control signals to determine that the result should be manipulated, and generates a half-sum output which is used to produce a manipulated result based on the control signals. The half-sum output is combined with a previous carry bit to complete the sum operation. The control signals can invert the adder result, or force the result to be all 1's. These functions can be effectuated in a 3-way multiplexer that combines the operand inputs and control signals. For inversion, two separate logic circuits produce true and complement half-sums in parallel, and the appropriate half-sum is selected for the half-sum output. For a result of all 1's, a force_1 control signal pulls the half-sum output node to electrical ground and the final output is manipulated by gating the carry signals with the force_1 signal. The two functions are implemented without introducing additional delay.

Consistent with the present disclosure, a method and apparatus for providing a uniform spectral gain of an optical amplifier is provided. Namely, a “balancing” step is carried out in which an optical channel having the lowest power level input to an optical circuit, such as an dynamic gain equalizer (DGE), is assigned a zero “attenuation error” and is substantially un-attenuated by the DGE. The lowest power level optical signal does not require further attenuation and effectively serves as a reference power level, which the power levels of the remaining optical signals are set to. For example, remaining optical signals are assigned either positive or negative attenuation errors relative to the zero attenuation error based on optical signal input powers to the DGE and accumulated DGE attenuations over time. Those optical signals having a negative attenuation error are substantially unattenuated by the DGE, because such optical signals are adequately attenuated and do not require further attenuation. On the other hand, the DGE is controlled to attenuate those optical signals having positive attenuation errors to thereby flatten the output spectrum of the amplifier. In one example, interpolation techniques may be employed to control those portions of the DGE (e.g., attenuators or pixels) that do not receive a channel, such that adjacent pixels that receive channels may impart a desired amount of attenuation. In addition, further interpolation may be provided to appropriately control the DGE pixels, if the number of channels supplied to the DGE is different than the number of pixels of the DGE.

A method for rapid hierarchical image segmentation based on perceptually driven contour completion and scene statistics is disclosed. The method begins with an initial fine-scale segmentation of an image, such as obtained by perceptual completion of partial contours into polygonal regions using region-contour correspondences established by Delaunay triangulation of edge pixels as implemented in VISTA. The resulting polygons are analyzed with respect to their size and color/intensity distributions and the structural properties of their boundaries. Statistical estimates of granularity of size, similarity of color, texture, and saliency of intervening boundaries are computed and formulated into logical (Boolean) predicates. The combined satisfiability of these Boolean predicates by a pair of adjacent polygons at a given segmentation level qualifies them for merging into a larger polygon representing a coarser, larger-scale feature of the pixel image and collectively obtains the next level of polygonal segments in a hierarchy of fine-to-coarse segmentations. The iterative application of this process precipitates textured regions as polygons with highly convolved boundaries and helps distinguish them from objects which typically have more regular boundaries. The method yields a multiscale decomposition of an image into constituent features that enjoy a hierarchical relationship with features at finer and coarser scales. This provides a traversable graph structure from which feature content and context in terms of other features can be derived, aiding in automated image understanding tasks. The method disclosed is highly efficient and can be used to decompose and analyze large images.

The present invention relates to a direct current (DC) offset suppression circuit to suppress DC offsets occurring when a communication circuit where a complex filter is adopted performs self-mixing. The DC offset is suppressed by a DC feedback circuit adopted by a filter which is substituted for a complex filter in the communication circuit.

It is because phase changes of the complex filter cause output signal fed back to the input of the complex filter to generate phase differences. The present invention includes a phase compensation unit and a DC feedback unit. The phase compensation unit compensates a change in frequency between input and output of the complex filter for phase compensation. The DC feedback unit inverses and feeds back the compensated phase to an input of the complex filter.

Furthermore, in the present invention, a second light emitting source emitting a second laser beam for DVD and a first light emitting source emitting a first laser beam for BD are disposed across the third light emitting source. Thereby the phase propagation directions of coma aberrations in the first and second laser beams coincide with each other.

Techniques for calibrating non-linearities of ADCs are described, which can be applied whether or not the non-linearities change with frequency. When the non-linearities do not change (are static), the frequency of a calibrating signal is first estimated coarsely in a calibration mode, then a fine estimate is determined using the coarse estimate. These estimates are then used to predict the sinusoidal signal using a linear predictor. A Look Up Table (LUT) containing corrections to the ADC is derived from this result. The LUT is then used in a normal operating mode to correct the output of the ADC. In a case where the characteristics of the non-linearities of the input signal are dynamic and thus change with frequency, a frequency spectrum of interest is broken into several regions. In each of these regions, a frequency is identified and used as a calibrating signal to generate the corresponding LUT. During normal operation of the ADC, in a first method, the bin corresponding to dominant frequency of the signal is identified using a short-length FFT. This bin is used to select the appropriate LUT for operating on the output of the ADC to provide the calibrated output. In a second method used when dynamic input is expected, a single LUT is developed using the averages values from the LUTs determined from the various regions.
