摘要： In a process for producing cyclohexylbenzene, hydrogen, and benzene are contacted in a first reaction zone under conditions effective to produce a product effluent containing residual benzene in the vapor phase and cyclohexylbenzene in the liquid phase. The product effluent is separated into a first stream that is rich in residual benzene in the vapor phase as compared to the product effluent and a second stream that is rich in cyclohexylbenzene in the liquid phase as compared to the product effluent. At least a portion of the first stream is cooled to condense at least a portion of the residual benzene in the vapor phase to the liquid phase and produce a condensate stream. At least a portion of the condensate stream is recycled to the first reaction zone.

摘要： An apparatus and method for allowing color adjustments in display devices is disclosed The apparatus comprises a multi-resolution structure for providing color adjustments; and an interpolator for interpolating at least one offset of the multi-resolution structure. An apparatus and method in accordance with the present invention uses a combination of color look-up tables with different levels of resolution, followed by interpolation to provide a display process which has high resolution but utilizes minimal memory. In so doing, memory is used for high-resolution areas only where needed. The multi-resolution structure is a very good approximation to the theoretical mapping table in the areas where it is needed. At the same time, since the high resolution areas are localized, a significant reduction in memory storage is possible.

摘要： Methods and apparatus, including computer program products, implementing and using techniques for performing temporal motion vector filtering in digital video are disclosed. A recursive hierarchical process is used to determine a motion vector. In the recursive hierarchical process, a neighborhood of old motion vectors is filtered to generate a first estimated motion vector for an image patch in a pair of two image frames. The filtering process uses multiple vectors in a neighborhood around the old motion vector to improve the prediction of the first estimated motion vector. The temporal vector partitioning process separates motion vectors associated with an object from motion vectors associated with a background before selecting a best motion vector, which improves the selection process. The process also works well in the absence of object/background boundaries, as in this case the outlier (incorrect) vector or vectors will be separated out from the good vectors.

摘要： Methods and apparatus, including computer program products, implementing and using techniques for computing motion vectors in a digital video sequence are disclosed. A recursive hierarchical method is used to determine a motion vector by using multiple resolution levels of the image frames. A best motion vector is first determined for the lowest resolution level. The best motion vector is propagated to a higher resolution level, where some adjustments are made and a new best motion vector is determined. The new best motion vector is propagated to yet another higher resolution level, where more adjustments are made and another new best motion vector is determined. This process is repeated until the highest, original, resolution level has been reached and a best motion vector has been identified. The identified best motion vector at the original resolution level is used for performing motion compensation.
