Image blending
Previously, Poisson blending has been used for image blending including cloning an object onto a target background and blending pairs of source images together. Such Poisson blending works well in many situations. However, whilst this method is always workable, we have found that discolorations sometimes occur. We realized that these discolorations occur when the gradient of the source image is preserved too insistently, at the expense of preserving object and background color. In some situations object outlines become smeared or blurred. We develop a color preservation term and a fragility measure to address these problems. This gives a user additional control to obtain smooth compositions and reduce discoloration artifacts. |

Numerically robust implementation of spectral gamut mapping
Color management in which gamut mapping is performed in a spectral color space. The gamut mapping process includes a colorimetric gamut mapping step, in which a colorimetric projection of the source-side color is gamut-mapped into a colorimetric projection of the destination side's spectral gamut. To ensure that the resulting gamut-mapped colorimetric color can be inverted into a set of feasible points in the spectral gamut, an additional step is inserted into the gamut-mapping process. Specifically, a further projection is made of the gamut-mapped colorimetric projection, whereby the colorimetric color is projected onto within the numerical boundary of the colorimetric projection of the destination side's spectral gamut. This additional projection yields a numerically robust color space color, that largely avoids adverse effects that otherwise might be caused by “numerical voids” found in the floating point representation of numbers by digital computers. |

Stereo synthesizer using comb filters and intra-aural differences
A method for creating a stereophonic sound image out of a monaural signal combines two sub-methods. Comb filters decorrelate the left and right channel signals. Intra-aural difference cues, such as an Intra-Aural Time Difference (ITD) and an Intra-aural Intensity Difference (IID) separated channels.

Training sequence for wireless communication system
Disclosed is a system and a training sequence setting method for performing frame synchronization in a wireless communication system. A received signal is affected by a frequency offset due to an oscillator mismatch between the transmitter and the receiver, which is one of the main causes of performance degradation of frame synchronization. In a prior Constant Amplitude Zero Auto-Correlation (CAZAC) sequence, the larger the frequency offset becomes, the more conspicuously the performance degradation of the frame synchronization occurs. The proposed training is designed to maintain a prior CAZAC property during a differential detection so as to perform a differential detection-based frame synchronization sequence insensitive to the frequency offset. As a result of performance verification, the proposed training sequence indicates that its performance of the frame synchronization is irrespective of the frequency offset, and has a better performance than the prior CAZAC sequence and random sequence. |

Pipelined packet switching and queuing architecture
A pipelined linecard architecture for receiving, modifying, switching, buffering, queuing and dequeuing packets for transmission in a communications network. The linecard has two paths: the receive path, which carries packets into the switch device from the network, and the transmit path, which carries packets from the switch to the network. In the receive path, received packets are processed and switched in an asynchronous, multi-stage pipeline utilizing programmable data structures for fast table lookup and linked list traversal. The pipelined switch operates on several packets in parallel while determining each packet's routing destination. Once that determination is made, each packet is modified to contain new routing information as well as additional header data to help speed it through the switch. Each packet is then buffered and enqueued for transmission over the switching fabric to the linecard attached to the proper destination port. The destination linecard may be the same physical linecard as that receiving the inbound packet or a different physical linecard. The transmit path consists of a buffer/queuing circuit similar to that used in the receive path. Both enqueuing and dequeuing of packets is accomplished using CoS-based decision making apparatus and congestion avoidance and dequeue management hardware. The architecture of the present invention has the advantages of high throughput and the ability to rapidly implement new features and capabilities. |
