    摘要： A set of screens is provided for use in printing respective color separations in a halftone color printing process. This set of screens comprises at least two clustered-dot screens and the frequency and angle parameter values of the screens is such that the lowest frequency moiré produced by any combination of at least two frequency components, taken from the group comprising the first and second screen harmonics, for which the sum of the harmonic orders of the frequency components in the combination is less than a predetermined value, is of a sufficiently high frequency as to be substantially unperceivable to the human visual system; other moirés are also substantially unperceivable to the human visual system. The lowest frequency moiré serves to reduce the visibility of color changes caused by color plane registration variations. A printing system and method employing the screen set are also provided.

    摘要： Embodiments of the present invention are directed to application-service provision by application-service-provider centers to remote application-service consumers, including small businesses, medium-sized businesses, and other similarly-sized institutions and organizations, as well as to users of individual computers, such as home computers. Rather than executing applications at an application-service-provider center, the applications are instead distributed to remote client sites for execution by virtual machines controlled and managed by an application-service-provider center. Execution of the applications by virtual machines at remote client sites alleviates constraints and bottlenecks associated with communications between client computers and remotely executing applications, while providing management capabilities and security that allow the application-service center to manage application execution as if the remotely executing applications were executing within the application-service center.

    摘要： A neural network is trained and used to reduce artifacts in spatial domain representations of images that were compressed by a transform method and then decompressed. For example, the neural network can be trained and used to reduce artifacts such as blocking and ringing artifacts in JPEG images.

    摘要： A method for generating a clustered halftone representation of a continuous-tone image for printing includes applying a search technique. In the search technique, evaluation of a similarity between an initial halftone and the continuous-tone image includes application of an initialization filter to an initial error image that represents a difference between the initial halftone and the continuous-tone image. Evaluation of a similarity between each updated halftone, formed by modifying a previously-evaluated halftone, and the continuous-tone image includes application of an update filter that is different from the initialization filter to an updated error image that represents a difference between the updated halftone and the continuous-tone image. Relating computer program product and data processing system are also disclosed.
