Constant-slope bitrate allocation for distributed encoding
A bitrate allocation engine allocates bitrates for distributed encoding of source data. Upon receiving a chunk of source data, the bitrate allocation engine generates a curve based on multiple points that each specify a different visual quality level and corresponding encoding bitrate for encoding the chunk. Subsequently, the bitrate allocation engine computes an optimized encoding bitrate based on the generated curve and an optimization factor that is associated with different visual quality levels and corresponding encoding bitrates for multiple chunks of the source data. The bitrate allocation engine then causes the chunk to be encoded at the optimized encoding bitrate. Advantageously, the resulting encoded chunk is optimized with respect to the optimization factor for multiple chunks of the source data. |

Advanced interconnect with air gap
Ultra-low-k dielectric materials used as inter-layer dielectrics in high-performance integrated circuits are prone to be structurally unstable. The Young's modulus of such materials is decreased, resulting in porosity, poor film strength, cracking, and voids. An alternative dual damascene interconnect process incorporates air gaps into a high modulus dielectric material to maintain structural stability while reducing capacitance between adjacent nanowires. Incorporation of an air gap having k=1.0 compensates for the use of a higher modulus film having a dielectric constant greater than the typical ultra-low-k (ULK) dielectric value of about 2.2. The higher modulus film containing the air gap is used as an insulator between adjacent metal lines, while a ULK film is retained to insulate vias. The dielectric layer between two adjacent metal lines thus forms a ULK/high-modulus dielectric bi-layer. |

System and method for controlling user repeatability and reproducibility of automated image annotation correction
Systems and methods are disclosed for controlling image annotation. One method includes acquiring a digital representation of image data and generating a set of image annotations for the digital representation of the image data. The method also may include determining an association between members of the set of image annotations and generating one or more groups of members based on the association. A representative annotation from the one or more groups may also be determined, presented for selection, and the selection may be recorded in memory. |

Device and method for fine adjustment of the reconstruction plane of a digital combination image
A method and a device for fine adjustment of the reconstruction plane of a digital combination image from individual images of a digital radiology system. The device includes an interface for providing individual images of an object. The individual images have overlapping regions with one another. A distance controller, with which the distance A of the individual images can be changed. A processing unit calculates a current combination image from the individual images. The individual images are each shifted by the distance A in relation to one another. A display unit displays the current combination image from the individual images. There is also described an image evaluation system and/or digital radiology system which includes the device. |

XSlit camera
Light representing a scene is directed through a lens module coupled to an imaging sensor. The lens module includes: first and second cylindrical lenses positioned along an optical axis of the imaging sensor, and first and second slit-shaped apertures disposed on the respective first and second cylindrical lenses. A cylindrical axis of the second cylindrical lens is arranged at an angle away from parallel with respect to a cylindrical axis of the first cylindrical lens. The light directed through the lens module is captured by the imaging sensor to form at least one multi-perspective image. The at least one multi-perspective image is processed to determine a reconstruction characteristic of the scene. |
